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.
Recently, a groundbreaking study concluded that their treatment combining ultrasound with steroid injections was 95% effective in the treatment of plantar fasciitis.
Plantar fasciitis is a foot problem affecting the plantar fascia, a connective tissue in the heel. This condition is treatable, but in many cases can take up to a year to be effective.
Conventional treatments have included exercises, rest, arch supports, and night splints. If this proves to be inaffective, many patients undergo shockwave therapy. In shockwave therapy, sound waves are directed to the area where pain is experienced. This therapy can be affective, but is somewhat painful, and calls for several sessions. Even still, shockwave therapy does not always alleviate the pain caused by plantar fasciitis.
Luca M. Sconfienza, M.D., from the University of Genoa in Italy, conducted the study. The new treatment involves an ultrasound-guided technique with a steroid injection to the plantar fascia. It is a one time out patient procedure involving a small amount of anesthesia. Then an anesthetic needle punctures the affected area. This technique, known as dry needling, causes small amounts of bleeding that aid in healing the fesci.
It was discovered that 42 of the 44 patients involved in the study had their symptoms disappear entirely within three weeks. “This therapy is quicker, easier, less painful, and less expensive than shockwave therapy” Sconfienza stated. “In cases of mild plantar fasciitis, patients should first try noninvasive solutions before any other treatments. But when pain becomes annoying and affects the activities of daily living, dry-needling with steroid injection is a viable option," she added.
Hammertoe: No Walk in the Park!
Hammertoe is a painful deformity of the second, third, or fourth toe, frequently caused by improper mechanics—the way a person walks or the shoes they wear that do not allow room for the deformity. Similar to mallet toe and claw toe, hammertoe involves different joints of the toe and foot. Shoes that are too narrow or short for the foot, or have excessively high heels, can cause of hammertoe. Improperly sized shoes force the toes into a bent position for long periods, causing the muscles to shorten and bend the toes into the hammertoe deformity.
Other causes of hammertoe may be complications from RA (rheumatoid arthritis), osteoarthritis, trauma to the foot, heredity, or CVA (cerebral vascular accident). Symptoms of hammertoe include, but may not be limited to, pain and difficult mobility of the toes, deformity, and calluses or corns from toes abrading one another.
A patient experiencing symptoms of hammertoe should seek examination by a physician, specifically a podiatrist. Podiatrists diagnose and treat disorders of the foot. If the doctor finds the involved toes have retained some flexibility, treatment may involve simple exercise, physical therapy, and a better fit to shoes worn by the patient. Treatment often targets controlling the mechanics, such as walking, that cause hammertoe by using custom orthotics.
In more advanced cases, where the toes have become rigid and inflexible, the doctor may suggest surgery. The operation would consist of incising the toe to relieve pressure on the tendons. The doctor may re-align tendons and remove small pieces of bone in order to straighten the toe. The insertion of pins may be necessary to fix bones in the proper position while the toe heals. Usually the patient is able to return home on the day of surgery.
If surgery is necessary, it is important to follow the postoperative directions of your physician. Theses may include various stretches, attempting to crumple a towel placed flat against your feet, or picking up marbles with your toes. Striving to wear shoes with low heels and ample toe space will ensure healthy feet and toes. Avoid closed shoes and high heels. Laced shoes tend to be roomier and more comfortable. Shoes with a minimum of one half inch space between the tip of your longest toe and the inside of the shoe will provide adequate space, relieve pressure on your toes, and prevent hammertoe from re-occurring.
Some tips on feet may include purchasing shoes at mid-day as your feet are smaller in the morning and swell as the day progresses. Ensure that she shoes you buy are both the same size and have the store stretch shoes at painful points to provide for optimum comfort.
The term bunion refers to an enlargement of the base joint of the toe, the connection to the foot. This enlargement may be formed of swollen tissue or a bony growth, and is caused by the shifting of the bones in the big toe inward, toward the other toes of the foot. The area around the base of the big toe may become inflamed, red, and painful.
Genetic factors are important in the formation of bunions – people who get bunions are usually genetically predisposed to this bone displacement, and may cause its onset by wearing improperly fitting shoes, or by running or walking in a way that causes stress to the feet. Another common cause for bunions is wearing high heeled shoes. The weight of the body in these shoes pushes the toes into an unnatural position, possibly causing bone displacement.
A podiatrist who specializes in foot structure and bio-mechanics will be able to quickly diagnose bunions. Bunions must be distinguished from gout or arthritic conditions, so blood tests may be necessary. The podiatrist may order a radiological exam to provide an image of the bone structure. If the x-ray demonstrates an enlargement of the joint near the base of the toe and a shifting toward the smaller toes, this is indicative of a bunion.
Wearing wider shoes can remove the pressure on the bunion and reduce pain. High heeled shoes should be eliminated for a period of time as this type of shoe generally pushes the big toe outward toward the smaller toes. This may be enough to eliminate the pain associated with bunions; however, if pain persists, anti-inflammatory drugs may be prescribed. Severe pain may require an injection of steroids near the bunion. Orthotics for shoes may be prescribed which, by altering the pressure on the foot, can be helpful in reducing pain. These do not correct the problem, but by eliminating the pain, they can provide relief.
For cases that do not respond to these methods of treatment, surgery can be done to reposition the toe. A surgeon may do this by taking out a section of bone, or may rearrange the ligaments and tendons in the toe to help keep it properly aligned. It may be necessary even after surgery to wear more comfortable shoes that do not put undue pressure on the toe as the big toe can easily move back to its orientation toward the smaller toes.
