PART 4: WHY DO MY TOES, ANKLES AND FEET HURT AT NIGHT? DIABETIC FOOT DISEASE

Over the past month, I have discussed why venous and arterial disease as well as Raynaud’s Syndrome may cause pain in the feet and toes at night. Today, I want to discuss another one of the most common causes I see in my clinic for pain in the feet at night: Diabetic foot disease.

Interestingly, diabetes mellitus has Greek etiology and literally means sweet (mellitus) urine (diabetes).  Diabetes is a condition in which the body loses its ability to limit the amount of sugar in the blood.  The high concentrations of sugar result in the formation of harmful chemicals that can hurt the eyes, kidneys, and nerves all around the body, especially in the feet.  Once the sugar levels become high enough, they overload the kidneys—the organ that creates urine—and sugar overflows into the urine, hence the Greek etiology of diabetes mellitus.

Diabetes causes pain in the feet via two main pathways: Neuropathic pain and pain from ulcers. 

Neuropathic Pain:

For neuropathic pain, the high blood sugar levels damage the small nerves in the feet responsible for sensation.  As a result, patients often complain of burning, cramping, tingling, and at the very worst end of the spectrum, numbness.  Sometimes only the toes have these symptoms, but often times the symptoms can encompass the entire foot!

Ulcerative Pain:

The way diabetes results in the formation of ulcers is multifactorial.

  • First, the damage to the nerves can result in numbness or lack of sensation.  Thus, when a person injures their foot, that person does not feel it and protects it from further injury.
  • Second, in addition to damaging the nerves responsible for sensation, diabetes also damages the nerves that innervate muscles responsible for moving.  The damage to the muscle nerves occurs in such a way that irregular contractions of muscles within the foot push the bones of the foot outward creating pressure points that ulcerate easily.  Once the ulcer is formed, infection of the ulcer or exposure of the raw tissues beneath the skin can cause pain.  In patients who otherwise have numb feet, an infection can spread to an area that does have sensation and cause pain there.

Given that diabetes is so common, patient education is vitally important to those impacted by this disease.  If you or anyone you love suffers from diabetes, my hope is that this blog will help you to better understand some of the underlying factors that may be contributing to your foot pain at night.  As a rule of thumb, always remember to share with your primary care physicians all symptoms of pain that you experience during your regularly scheduled appointments and if you think your condition may be getting worse, please do not hesitate to call my office to schedule an appointment for a second opinion!

PART 3: WHY DO MY TOES, ANKLES AND FEET HURT AT NIGHT? PERIPHERAL ARTERIAL DISEASE

In part one- and two of our four-part series on “Why do my feet hurt at night”, I discussed Venous disease and Raynaud’s Syndrome. In today’s discussion I want to focus on an even more common reason for why patients may suffer from leg pain at night: Peripheral arterial disease (otherwise known as PAD.)

As we’ve discussed in our earlier blogs, there are two kinds of blood vessels: Arteries and veins.

  • Arteries bring blood from the heart to the foot and toes under high pressure while
  • Veins bring the blood back from the foot to the heart under low pressure.

Over the course of anyone’s lifetime, blockages may build up in the arteries between the heart and the feet, especially in the pelvis and the legs.  Risk factors that increase the risk of formation of these blockages include:

  • Obesity
  • High blood pressure
  • High cholesterol
  • Diabetes
  • History of smoking tobacco.

As you may imagine, the tissue within the foot needs a certain amount of blood to supply the nutrients and oxygen necessary to keep the cells within the foot living.  Though a single, short segment blockage of the arteries in the leg may not result in any problems, multiple blockages from the pelvis to the foot may can make it difficult or even impossible for the cells within the foot to survive this lack of nutrients and oxygen.

What Does PAD Feel Like?

Typically, patients notice a gradual onset of pain in the forefoot and toes over the course of a few weeks to months.  As their blockages worsen, their pain becomes more severe.  Pain from PAD occurs in the forefoot and toes because those parts of the body are the furthest away from the heart and thus any blockage along the way from the heart to the toes can contribute to the lack of blood flow. One classic symptom of PAD pain is a burning, tingling, or numb sensation that can be partially relieved by hanging your foot off the bed or a chair.  In this position with the foot hanging down, gravity assists the flow of blood to the foot and toes and relieves the pain.  Typically, patients complain that when they lay flat at night, the pain in the forefoot and toes or just the foot in general will wake them up.  I always specifically ask patients if they are woken up at night by the pain.  If they are woken up by the pain, then I know the PAD must be very severe.

In some patients, the lack of blood flow is so diminished that there is also the development of ulcers, or defects in the skin with exposure of underlying fatty tissue, bone, and muscle or gangrene, the death of the tissue itself.

Even though PAD is a very severe and life limiting disease, specially trained vascular surgeons have many tools to combat it!  We can do a minimally invasive procedure called an angiogram that I described in an earlier blog post that you can access here!  Essentially, I access the diseased blood vessel with a needle and through that needle use contrast and x-ray to see where the blockages are.  Then, using balloons, stents, or self-expanding metal tubes, it is possible to re-open the blockages to re-establish blood flow to the impacted area.  For severe blockages, I also use a device called atherectomy that allows me to cut through and to remove the plaque responsible for blocking this vessel.  The procedure on average takes 1.5 to 2.5 hours and most patients can go home the same day.

PART 2: WHY DO MY TOES, ANKLES, AND FEET HURT AT NIGHT? RAYNAUD’S SYNDROME

Last week I wrote the first part of a four-part series about foot pain at night.  Specifically, I talked about venous disease as a cause of foot pain.

Today, I want to talk about another common cause of foot pain at night: Raynaud’s Syndrome. 

As a quick review, last week we talked about the two main types of blood vessels in our bodies: arteries and veins.  Arteries bring blood from the heart to the feet under high pressure.  Veins bring blood back from the foot to the heart under low pressure.

Raynaud’s Syndrome is a disease of the arteries, particularly the small arteries, in the feet.

(Though Raynaud’s can also affect the hands as well). 

Before we dive into Raynaud’s Syndrome though, I need to briefly review another anatomical system in our bodies that is involved in Raynaud’s Syndrome: The nervous system.

In general, we have two broad types of nerves.

  1. There are nerves that are responsible for sensation and for moving muscle and
  2. There are nerves that are responsible for regulation of bodily function.

Diving a little bit deeper into the kinds of nerves that regulate bodily function, there are the

  • Sympathetic nervous system: The sympathetic nervous system, amongst other things, is responsible for opening blood vessels in the legs and arms and increasing blood flow when exercise is necessary
  • Parasympathetic nervous system: The parasympathetic nervous system in similar fashion opens the blood vessels leading to the intestines to allow for the digestion of food.

In patients with Raynaud’s Syndrome, sometimes their sympathetic nervous system does not function properly resulting in the constriction of blood vessels that lead to the hands, fingers, feet, and toes.  When it happens, blood vessels in the fingers and toes typically first turn blue because of the lack of oxygen; then white because of the lack of blood flow; and finally red, once the constriction ends and the blood flow returns to the fingers and toes.  During this constriction of the blood vessels, patients can have significant pain, numbness, tingling, and, in very severe cases, ulcers (defects in the skin with exposure of underlying fat and muscle) and gangrene (black and dead tissue).

Interestingly, environmental and social triggers play a significant role in Raynaud’s Syndrome episodes of vessel constriction.  Factors including stress, caffeine, alcohol or other drugs, and cold temperature can all induce a painful episode with lack of blood flow to the hands and feet.

Not much is known about the cause of Raynaud’s Syndrome or specifically why it happens.  Sometimes, Raynaud’s Syndrome can occur on its own without any other related disease.  In other cases, the patient has another inflammatory disorder like lupus or Sjogren’s Syndrome that is known to be highly associated with Raynaud’s Syndrome.

Though we do not fully understand the causes of Raynaud’s Syndrome there are many treatment strategies that can help.  Starting with behavioral modifications and certain blood pressure medications that can reduce spasm to specific procedures aimed to reduce the spasm of the vessels induced by the sympathetic nervous system, there is so much that I as a vascular surgeon can do to help patients with Raynaud’s Syndrome.  If you think that you might suffer from Raynaud’s Syndrome, please do not hesitate to call our office on 408-376-3626 to schedule an appointment.

PART 1: WHY DO MY TOES, ANKLE, AND FEET HURT AT NIGHT? VENOUS DISEASE

One of the many questions I receive as a vascular surgeon is why do my feet hurt at night?  Though this question may seem simple, every person is different. Before I can provide you with “real” solutions to what’s causing this pain and what can be done to stop it, I need to evaluate multiple factors to understand “Why” this pain exists.  Over the next few weeks, I am going to explore the most common reasons for foot pain at night and why people can have pain in their feet at night caused by venous disease.

For the majority of patients Raynaud’s syndrome, Arterial disease, and Diabetic foot disease explain most of the reasons why people experience pain in their feet at night.  Though pain from problems with bones and muscle can play a role, pain due to these causes usually worsens during the day and with use, not when a patient is resting or lying flat.

In part one of this four-part series, I am going to discuss pain at night caused by VENOUS DISEASE.

Let’s start with a refresher on our bodies “plumbing” (Specifically, how does blood circulate around my body.)

  • Veins are blood vessels that bring blood BACK from the feet to the heart.
  • Arteries on the other hand are the blood vessels that bring blood FROM the heart to the feet.

Veins have specialized structures called one-way valves that allow blood to go up towards the heart but not back down towards the feet.  As we age, veins become dilated (start to leak) because the valves no longer seal properly. These leaky valves allow blood to fall back towards one’s feet which results in an increase in pressure within the veins at the ankle and just above the legs. Gravity tugs on the blood in our veins bringing it down to our feet which causes this increase in pressure

Interestingly, because of the curve that the veins take at the level of the ankle to enter the foot, the increase in pressure is not transmitted directly to the foot and toes.  The increase in venous pressure at the ankle typically results in

  • Varicose veins,
  • Swelling,
  • Dark skin discoloration from the leaking of red blood cells into the skin, and, in the worst cases
  • Ulceration.

Even without ulceration, however, the pain related to swelling and discoloration can be very severe.

People during their normal daily lives spend most of their days either standing or sitting.  Because of this, during the day gravity works in both positions to facilitate the pooling of blood around one’s ankles.  When patients come to me with pain in their feet, I always ask specifically if the pain is localized in the calves and ankles.  When pain is localized to the calves and ankles, I confirm a venous etiology by performing a physical exam and finding varicose veins, swelling, dark skin discoloration and/or ulcers between the ankle and the knee.

Pain that is reported in the foot and/or toes without the physical exam findings of varicose veins, swelling, dark skin discoloration, and/or ulcers between the ankle and the knee is NOT likely to be from a venous cause!  Though vein problems may sound or seem like a rare disease for those who have never had venous disease, patients with vein problems are one of the most common consults I see as a vascular surgeon.  Does foot pain wake you up at night? If you have any of the symptoms or appearance of the leg that I described above, please do not hesitate to call our office on 408-376-3626 to schedule an appointment.

One Final Note:

Though causes from the bones and muscles can play a role, foot pain that worsens at night is rarely due to these causes.  Often pain related to problems with bones and muscles worsen during the day and with use, not when any given patient is resting or lying flat.

Clues that can guide me as a vascular surgeon to the cause include throbbing and aching pain versus numbness and tingling associated with tenderness or pain located in the toes versus pain located in the ankle or just above the ankle in the leg.

FIXING BLOCKED ARTERIES

The most common disease that I treat as a vascular surgeon is a medical problem called peripheral vascular disease.  Specifically, peripheral refers to the legs, and vascular disease refers to blockages of the arteries.

Because peripheral vascular disease is the most common disease that I treat, I want to talk today about what I can do as a vascular surgeon to fix these kinds of blockages in the arteries!

First though, let me explain why blockages to the arteries of the legs are bad.  When not enough blood flow reaches the legs, patients can have pain in their calves or buttocks that limits their ability to walk longer than a city block.  When the blockages are very severe, they can also have pain in their feet and toes even when they are not moving or develop non-healing ulcers and gangrene.  When I open blockages in patients’ legs, I allow them to walk again, or I give them the ability to heal their ulcers and gangrene pain free.  The improvement in patient lives is the most exciting aspect of my job!

There are two main approaches to performing what we call revascularization. Revascularization refers to the opening of old passageways or creation of new passageways to bring blood directly from the heart to the foot without any obstruction.

  • Open Surgery: In the early decades of vascular surgery, namely the 1980s and 1990s the primary way to treat peripheral vascular disease was to perform an open surgical bypass.  If there was a blockage in the thigh, I would surgically expose above and below the blockage and take a synthetic tube or the patient’s own vein and then sew it above and below the blockage.  This would allow the flow of blood to bypass the blocked segment, hence, the reason we call this surgery a bypass!  Though this procedure does produce robust flow, it necessitates large surgical incisions that cause significant pain and are susceptible to poor wound healing and/or infection.

 

  • Endovascular Surgery: In the 2000s, an innovative approach called endovascular surgery started to become more widely used and is now actually standard of care today.  Indeed, I prefer to treat patients with peripheral vascular disease with endovascular surgery whenever possible.  We access the arterial system of the leg with a needle in the groin.  Through that needle we put in a strong wire and over that wire we can then advance several different instruments over catheters.  In general, there are three different techniques I can employ in my efforts to re-establish blood flow to an area that is no longer receiving blood due to some type of arterial blockage.
    • Balloons: The most basic instrument is a balloon that expands and breaks up the narrowing or blockage.
    • Stents: If the balloon does not work, we can use a self-expanding tube called a stent.
    • Atherectomy: If the stent does not work, we can use a special device called atherectomy.  Atherectomy involves the use of a device that can literally cut the plaque out of the artery and aspirate all the debris.

 

These three technologies allow the reopening of arteries from the toes to the pelvis and only necessitate a 2 mm puncture site in the skin of the groin to be used.  There is little to no risk of infection and the procedure can be performed several times over the course of the patient’s life.  On the other hand, surgical bypass can only be performed twice—three times—during the patient’s life due to the development of dense scar tissue after each operation.

 

If you have trouble walking because of pain in your buttocks or calves or have pain in your feet and toes or ulcers that will not heal, please do not hesitate to call my office today at 408-376-3626 to schedule an appointment.  The chances are that I will be able to help take your pain and ulcers away!

WHY DIABETES IS BAD FOR YOUR FEET

Everyone knows that diabetes, otherwise known as high blood sugar, is bad for you.  What most people don’t realize, however, is just how many people in the US have diabetes and the impact diabetes has on their feet. In 2021 the CDC released the following info graphic:

 

As a vascular surgeon the primary issue I see in patients with diabetes is foot infection.  But how does diabetes specifically make it more likely for patients to develop foot infections?  My hope in writing this blog today is to give patients a complete understanding of what happens to the feet of people with diabetes.

High concentrations of sugar in the blood lead to what physicians call an inflammatory state in the arteries, or blood vessels that take blood from the heart to the rest of the body.  The inflammatory state results in scarring and narrowing in the arteries.  However, only smaller blood vessels such as the ones in the eyes, toes/feet, and kidneys are affected significantly.  In the feet, the scarring affects both arteries that supply the feet and toes themselves as well as the arteries that supply the nerves.

With a lack of blood flow to the nerves of the feet, patients lose sensation in their toes and feet.  Thus, when a patient has an accidental injury like a scratch or a bruise, no pain is registered, and the area continues to be traumatized and unable to heal.  In addition, the muscles of the foot lose their ability to contract, and they then relax into positions that create bony prominences that erode through the skin and cause ulcers.  Finally, the nerve damage also results in the loss of natural oils in the skin that then makes the skin dry and prone to cracking.  This cracking then increases the chance of ulceration and foot infection.

As you can see, diabetes is very bad for the foot!  If you are diabetic and see an ulcer on your foot or have either pain or numbness, do not hesitate to call our office at 408 376-3626 to schedule an appointment today! Visit our website at www.southbayvascular.com to learn more. We Can Help!

WHY DON’T THE WOUNDS ON MY LEGS AND FEET HEAL ANYMORE?

Hi! Dr. Lau here again with South Bay Vascular. Today, I wanted to shed some light on one of the most common issues that we see in vascular surgery, non-healing wounds of the feet and toes. My hope is that after reading this blog you will have a better understanding of what causes leg wounds and ulcers; why sometimes they won’t heal on their own, and what we in vascular surgery can do to help them heal.

Ulcers, generally speaking, develop because of TWO main causes: nerve damage induced by diabetes and lack of blood flow. When patients have elevated levels of sugar in their blood with diabetes, the sugar forms toxic compounds that damage nerves in the foot. Consequently, the patient cannot feel injuries that would otherwise cause a normal patient to adjust position to stop the injury. With this loss of sensation ulcers form at the point of repeated injury that the patient cannot feel.

The second cause, a lack of blood flow, develops over decades in patients who smoke and who have high blood pressure and high cholesterol. These medical problems cause hardening and narrowing of the blood vessels, otherwise known as atherosclerosis.

In patients with diabetes, I coordinate carefully with my podiatrist colleagues who are experts in specialized footwear and surgical interventions that alleviate common areas of trauma. In patients with poor blood flow, I, as a vascular surgeon, can perform minimally invasive surgery to restore blood flow to the affected area. We use wires and specialized tubes to gain access to the blood vessels and then use balloons to break open the narrowing’s and self-expanding tubes called stents to keep the vessels open. Afterwards, we use a specialized x-ray machine called fluoroscopy to see that the narrowing’s have opened again to allow blood to flow back to the area. Patients usually leave to go home the same day with only a 2-millimeter puncture in their groin and are back to normal activity the day after surgery!

LEG SWELLING: SYMPTOMS AND SIGNS

Do you Suffer From Iliac Vein Compression?

To answer that question, take a few seconds to consider the following:

  • Are your legs swollen? Is your left leg larger than your right?
  • Is it harder to slip one shoe on in the morning than the other?
  • Have you had cosmetic or other surgical procedure done and not gotten the outcome you wanted?
  • Are you a cancer patient undergoing treatment or procedures?
  • Have you ever suffered from a blood clot or (DVT) in your leg
  • Do you visit a wound care clinic with little to no success?

If you’ve answered yes to any of these questions, you MAY be suffering from a well known, but previously difficult to diagnose problem called May-Thurner’s Syndrome.

May Thurner’s Syndrome, also known as iliac Vein Compression, is a condition where the main artery supplying blood to the leg pushes down or compresses the main vein taking blood back to your heart. In the illustration below you can see in the far right graphic a “representation” of this compression. One way to help think of what happens when a patient suffers from iliac vein compressions is to consider what happens when a car tire partially runs over a garden hose in your driveway.

If the hose was “on” when you drove over it, water will continue to come out of the hose end but the flow rate will decrease. In a similiar way, blood returning to your heart will continue to flow if you have developed iliac vein compression, but the rate at which it returns is slowed down, resulting in a pooling of blood (i.e. swelling) in your leg.

Chronic pain and swelling in one leg (especially the left side) may be caused by Iliac Vein Compression. This is a little-known but fairly common condition that can greatly impact your quality of life—and may lead to more serious complications. In fact, studies have shown that in a full 30% of ALL people, the left iliac vein can be significantly compressed by the right iliac artery resulting in some kind of leg symptom….aching, heaviness, and most commonly, swelling or non-healing of wounds in the leg veins.

Swollen legs ARE NOT a normal part of aging or weight gain. And it’s not something you have to “just live with.”

Leg swelling is a special area of interest of Dr. Polly Kokinos, and she has been active in doing clinical research to find better ways to diagnose and to treat this condition. To diagnose and to treat this condition and the potentially deadly side effects caused by it (Blood Clots or Deep Venous Thrombosis) Dr. Kokinos has assembled a highly skilled team of vascular ultrasonographer’s who have developed a specialized screening protocol to evaluate for Iliac Vein Compression. Using state of the art ultrasonic imaging technology Dr. Kokinos’ Registered Vascular Ultrasonographer’s use this new protocol to scan up into the abdomen of their patients to examine the physics of the blood flow in this area. If a compression is identified during this ultrasound exam, Dr. Kokinos is able to further verify and treat this problem using a super specialized device called IVUS (Intra-vascular ultrasound) where she can insert a miniuture camera into the actual vein to determine the length of the compression after which she can place a stent to “re-open” this compressed vessel to re-establish normal blood flow.

To date, Dr. Kokinos has successfully performed over 200 of these iliac vein stent procedures in her state of the art out-patient angiography suite. She has lectured extensively at major vascular surgery meetings on her approach and success helping patients reduce leg swelling, increase the rate of wound healing and return to a normal way of living and is seen by her peers as an expert in this technique.

If you are currently experiencing a swollen leg, have a non healing leg, foot,or ankle wounds or have ever suffered a blood clot (DVT) please contact our office at 408-376-3626 to schedule an appointment.

Don’t suffer from swollen legs or non-healing leg ulcers any longer.

WHY DIABETIC FOOT WOUNDS DON’T HEAL

One of the main complications of diabetes is the development of diabetic foot ulcers. Diabetic foot ulcers occur in 15% of all patients with diabetes. There are four primary contributing factors to the developments of these ulcers.

  • The presence of peripheral neuropathy (loss of feeling over the toes);
  • Changes in the architecture (shape) of the foot causing it to have pressure on areas ot built for it;
  • Poor blood flow to the foot;
  • A decreased ability to fight infection in the foot.

The main reason why diabetic wounds do not heal is due to lack of blood flow to the ulcer and ongoing pressure to the wound

Diabetics must pay special attention to their feet and ankles and it is vitally important to NOT ignore a small wound when it develops. Diabetic wounds, when left untreated, are the cause of 85% of the amputations that occur in these patients. Once these ulcers develop, they often DO NOT HEAL just by putting a Band-Aid over them, or even with wound care and ointments prescribed by your primary care doctor.

Care of Diabetic Foot Wounds

It is very important to see both a podiatrist (foot specialist) and a vascular surgeon (blood flow specialist) to examine your foot. These doctors can help with special treatments such as debridement (cleaning the wound), off-loading (taking pressure of the wound) and improvement of blood flow to help your wound heal. Debridement helps remove dead tissue and bacteria from the wound. Off-loading and special inserts or shoes allow the pressure to be removed from the wound so that it can heal. Diabetes causes blockages with calcium deposits inside your small blood vessels, which are below the knee, and this prevents oxygen and nutrients from getting to your feet. The vascular surgeons at South Bay Vascular Center have a special interest and expertise in opening these blood vessels in order to bring flow to your toes and feet that can help save patients from amputation. If you or anyone you know suffers from diabetes and are experiencing foot wounds that do not heal, call us immediately at 408-376-3626 to schedule an appointment to have these wounds evaluated.

TREATING DIABETIC FOOT ULCERS

Millions of patients every year are seen in wound care centers for the treatment of their foot and leg ulcers. This is absolutely the correct place for anyone who has had a wound that is “non-healing” or “chronic”. That is, a wound that is still there after four weeks. Unfortunately, sometimes the physicians in these wound care centers are quick to put on expensive savs or other advanced treatment options. After all, isn’t that why the patients go to the wound care center instead of just their physician’s office? Partially. Good wound care centers treat by guidelines.

Guidelines are a scientifically proven set of steps that have been shown to help wounds heal faster. For EVERY wound on the leg or foot, the very first step is to assess BLOOD FLOW. This means that every patient with a leg or foot wound that hasn’t healed in four weeks MUST be seen by both a vascular surgeon AND a podiatrist (foot specialist).

The vascular surgeon will assess the circulation and order appropriate diagnostic tests, such as vascular ultrasounds to look at the blood flow. This is important to examine, as a large number of the patients who have ulcers, have not previously been diagnosed with an arterial or venous problem. Without fixing the underlying cause of the ulcer, even if it does heal initially, it will soon recur, and cause further problems. It is important for patients to take an active role in asking for these referrals so that the problem does not progress and become a wound that can lead to an amputation.

If you or anyone you know is diabetic and suffers from non-healing leg wounds call today to schedule an appointment at our office. South Bay Vascular Center and Vein Institute Surgeons are recognized as the regional experts in wound care healing and amputation prevention. Our Vascular Surgeons have performed more lower extremity re-vascularizations than any other surgeons in the region and offer hope when others say there is none.
