Causes, Symptoms, and Treatment of Poor Blood Circulation in the Feet

Poor blood circulation in the feet and legs is often caused by peripheral artery disease (PAD), which is usually the result of a build up of plaque in the arteries. Plaque build up, or atherosclerosis, can be the result of excess calcium and cholesterol in the bloodstream, which restricts how much blood can flow through arteries. Reduced blood flow to a certain area of the body severely limits the amount of oxygen and nutrients that part of the body receives, causing degeneration in the muscles and other tissues. Sometimes, poor blood circulation in the feet and legs can be caused by other conditions, such as damage to or inflammation of blood vessels, known as vasculitis.


The lack of oxygen and nutrients caused by poor blood circulation can restrict muscle growth and development, as well as cause muscle pain and cramps, weakness, and stiffness. Other common symptoms include numbness in the legs and feet, skin discoloration in the affected limbs, slower nail and hair growth, and erectile dysfunction in men. In more severe cases of PAD, pain can be present even when a person isn't exercising, and may range from mildly uncomfortable to completely debilitating.

Poor blood circulation in the feet and legs is more common in those who are overweight or obese, have diabetes, high blood pressure, high cholesterol, who smoke, or who have a family history of PAD or related conditions (heart attack, stroke, etc.). Diabetes and smoking place a person at greatest risk for developing poor blood circulation, although advanced age (over 50) can also increase risk.

If you are experiencing poor blood circulation in the feet and legs caused by PAD, it is important to make changes to your lifestyle in order to reduce your risk of experiencing a heart attack or stroke caused by this condition. If you smoke, quit completely -- this will increase the amount of oxygen in your bloodstream. Exercising and reducing the saturated fats in your diet (which come from fatty meats, fried foods, whole milk, etc.) can make a difference in improving blood circulation in feet. It is also important to avoid developing influenza and to carefully control your blood sugar if you have diabetes.

Your doctor may recommend combining lifestyle changes with a prescription medication regimen to improve blood circulation. The most commonly-used medications for PAD are called statins and work by blocking the amount of enzymes in your body that produce cholesterol. They are known by the brand names Zocor, Lipitor, Crestor, and others.

Systemic Diseases of the Foot

There are several systemic diseases, or diseases that affect the whole body, that either display symptoms in the feet or affect the health of the feet. Common systemic diseases that affect the overall health of the feet, and the patient’s ability to walk comfortably, include gout, diabetes mellitus, neurological disorders, and arthritis.


In gout, which is caused by an excessive buildup of uric acid in the body, the most common symptoms of pain, inflammation, and redness occur at the metatarsal/phalangeal joint at the base of the big toe. Any excess levels of uric acid, crystallize and are deposited in tendons, joints, and surrounding bone and muscle tissue. Gout is commonly treated with NSAIDs to relieve pain and inflammation and other drugs to lower uric acid levels in the body. Gout most commonly affects those who are overweight, have low protein diets and lead a more sedentary lifestyle.

Diabetes mellitus is an increase in the level of blood sugar in which the body cannot counteract with naturally occurring insulin in the body. The three types of diabetes, Type I, Type II and Gestational Diabetes, are all signs the body is either not producing enough insulin or is not efficiently using the insulin that is produced. Gestational diabetes only affects women who are pregnant and have never, prior to pregnancy, exhibited symptoms of the disease.

There are two main issues that affect the feet that are commonly caused by diabetes. They include diabetic neuropathy and peripheral vascular disease. Diabetic neuropathy can lead to damaged nerves and affect the feet through numbness and loss of sensation. Peripheral vascular disease restricts the flow of blood to the foot and can, in extreme cases, lead to the necessity of amputating the foot. Peripheral issues that are caused by diabetes and can affect the foot include athlete’s foot, nail infections, corns, blisters, bunions, severe dry skin, plantar warts and ingrown toenails. These can all be attributed to the decrease of blood flow to the foot.

Neurological disorders and rheumatoid arthritis can also have severe impact on the health of the feet. Neurological disorders can affect the nerves in the main structure of the foot and cause loss of sensation and possible decreased muscle response. Rheumatoid arthritis can affect the bones and joint structures of the foot, making it impossible to walk normally without serious pain.

All systemic diseases that affect the foot can effectively be treated to minimize joint and muscle damage if they are diagnosed early and treated with medication and lifestyle therapy. Diabetes patients must monitor their blood sugar levels and work with their physician to keep their levels as close to normal as possible. Rheumatoid arthritis patients should work with their physician to ensure the proper medications are being taken to reduce the amount of damage to the joints of the body.

Corns: What Are They, and How Do You Get Rid of Them

Corns are areas of the skin where it has thickened to the point of being irritating and sometimes painful. Corns are circular or cone-shaped and are commonly found on the feet where there are areas of pressure or friction, such as on the little toe where it may rub against shoes or on the ball of the foot. The medical term for corns is helomas.

Corns can easily be confused with a callus, but there is a difference between the two. Corns can be a raised bump that feels hard to the touch and painful. They consist of a thick, rough area of skin that may be dry and waxy. Corns tend to be surrounded by inflamed skin and are usually smaller than calluses.

The key to treating a corn is to remove the dead skin that has built up. Salicylic acid is the most common medication used to accomplish this. Salicylic acid works by dissolving keratin, the protein that makes up the majority of corns. You can purchase salicylic acid over-the-counter in the form of wart removers. It comes in medicated pads, drops or creams. People with diabetes should not use salicylic acid, but should immediately consult their doctor.

To treat corns, apply the medication directly onto the corns according to the product directions. The top layer of the corn will turn a white color. When that happens, the layers of skin can then be peeled away, making the corn smaller. It is never a good idea to try and shave off corns with razors or other pedicure equipment. This can lead to infection. If your corns get infected or do not respond to over the counter treatment, a visit to the doctor is necessary.

Orthotic inserts fitted by a podiatrist also help to treat corns and help prevent their return. Inserts fit into shoes and help to adjust the way your foot fits in your shoe, thus fixing the way you walk. This will reduce friction, lowering your chances of getting a corn and eliminating the pain for current corns.

Surgery is seldom an option for corns, but does occur on rare occasions. Surgery for corns actually deals with the underlying issue causing the corns. During surgery, the bone is shaved and any abnormalities are corrected to reduce the amount of friction that occurs during walking.

The first step to preventing corns is to reduce any possible friction. Wear well fitting shoes that don’t rub on your feet. If you notice rubbing developing, pads can be purchased to help reduce the friction. These can be purchased over the counter and are simply placed on the area that is being irritated. Friction can also be reduced by using cushioned insoles in your shoes, and making sure to wear well-fitting shoes. This will make sure your foot is not being squeezed awkwardly, and stop corns from forming in the first place.

Diabetic Foot Care

Diabetes affects millions of people each year. Diabetes damages blood vessels in all parts of the body, including the feet. The legs and feet may have slow blood flow which causes neuropathy (nerve damage). Once a diabetic patient develops neuropathy, it is imperative that the feet are well taken care of to avoid amputation of the feet or legs.

It is important when caring for the feet of diabetics to always wash and thoroughly dry the feet, especially between the toes. Next, examine your feet and toes for any redness or sores that may be there, even if you do not feel any pain. You may also use a mirror to examine your feet from the bottom side. Avoid wearing colored socks to prevent infections that may occur from the dye used in them. Well-fitting socks are also highly recommended.

Anyone with diabetes should have their physicians to monitor Hemoglobin A1C levels as this test lets the physician know how well the blood sugar levels have been controlled during the past 3 months. It is very important to keep the blood sugar levels in the normal range (70-110mg/dl). There are medications that a physician may prescribe to help with neuropathy of the diabetic patient. It is also advisable to visit a podiatrist if the diabetic patient is experiencing any conditions involving the feet. Toe nails may need to be taken care of by a podiatrist as some patients may cut to deep or not deep enough around the cuticles and risk having an infection that could occur.

While at home a person can take care of their feet if they follow instructions given by their physician or nurse. An effective treatment is using creams and applying them to the heels due to the possibility of extreme dryness. Be careful when using tools to remove the calluses as severe diabetics may not be able to feel pain, and this can cause a severe wound to develop.

Diabetic feet absolutely need to be inspected on a daily basis. Always notify your health care professional with any concerns that you may have about the care of your feet. Waiting to see if a wound will get better is not a good idea as it can turn into a life threatening condition. Gangrene is a serious problem for diabetics and can lead to sepsis and amputation. Early treatment and daily inspection of the diabetic feet are keys to staying healthy.

Stretching Your Feet

Debilitating foot pain is a problem for many people. But just as stretching the torso can help alleviate back pain, stretching the feet can also mend existing problems and prevent future ones.

The feet carry the entire weight of the human body all day and can get easily strained from overexertion. Persistent sharp pain and cramping in the feet are common problems. Foot pain and problems can be due to any number of causes, and in many cases pain may be eased without medication or doctor visits; however, it is always a good idea to rule out any serious medical issues first with a physician.

Stretching may help relax the feet and alleviate pain at any time, but it is especially important before    heavy aerobic exercise to avoid painful cramps or straining muscles in the feet. Stretches should be performed slowly and deliberately without forceful pulling. The stretch should be held for several seconds, and then relaxed.

A great way to stretch out and loosen up the foot muscles while sitting is to cross one leg over the other and pull the toes carefully back without overextending. Start by resting the left ankle on the right knee. With the left hand, gently flex the left foot by pulling back on the toes. Do not pull too hard, just hard enough to feel the stretch in the arch of the foot. Then point the toes of the left foot as far as you can. Rotate the motion of pointing with pulling back on the toes. This should relax and stretch the muscles on the bottom and the top of the foot. Doing this stretch ten to twenty times should bring relief. Repeat the whole process for the other foot by resting the right ankle on the left knee.

A stretch that focuses on the often injured Achilles tendon involves standing, facing a wall, with your arms out and hands flat against the wall. Step back with one foot, keeping it flat against the floor. Move the other leg forward and lean toward the wall. You should feel a stretch through the back of your leg and your Achilles tendon, but do not push yourself too much. Stop when you feel the stretching sensation and hold for 30 seconds. Ten repetitions may be done for each foot.

Stretching the feet is important for athletes or those performing aerobic exercise, but it can also help anyone with foot pain caused by poor footwear, plantar fasciitis, or long hours standing and walking. Individuals who tend to their feet by regular stretching every day should be able to minimize foot pain and prevent new problems from arising.
