Leg pain may be circulatory.

Leg pain, especially at night or leg pain after walking short distances (less than 3 or 4 blocks), could be a medical condition known as peripheral arterial disease. This involves narrowing of the blood vessels supply blood to your lower extremity. Plaque composed of fat and cholesterol builds up inside the walls of your arteries and restricts normal blood flow. This build up is known as atherosclerosis also known as hardening of the arteries. When it affects the heart it is called coronary artery disease (CAD) which can cause a heart attack. When it affects the arteries to he brain it is called carotid artery disease and can lead to a stroke.
Artherosclerosis in the arteries that supply blood to kidneys, stomach, arms, legs, or feetis called periperal arterial disease (PAD). Currently it is estimated this disease affects 8 million Americans and tends to incease with age and is present in a disproportionate number of African-Americans. Compated to other people, someone with PAD is six to seven times more likely to experience coronary artery disease heart attack, stroke, or a ministroke called a TIA (Transient Ischemic Attack). What is a disturbing statistic is half of the population with PAD do not have symptoms.
"One of the first signs of PAD can be painful cramping or fatigue in the legs and buttocks that occurs during activity but stops during rest," says Chacko Alexander, M.D. "PAD can also cause leg numbness, cold legs or feet, skin color changes in the arms or legs, toe or foot sores that don't heal quickly, hair loss on feet and legs, and burning or achy feet and toes when resting or lying down. In advanced stages, blood flow to a leg or foot can be severely blocked, causing tissue death that may result in amputation."
People diagnosed with PAD usually can be treated with lifestyle changes, medications, or a combination of both. In some instances, however, surgery may be necessary to open vessels using a variety of techniques.
If you exprience any of these symptoms and are African-American, older than 40, female on birth control pills, diabetic, smoke, have a history of heart disease or a family member with PAD or CAD, consult your family doctor or see a Podiatrist for an evaluation.
