|Lower-Leg Pain When Walking: 3 Causes|
by William J. Doherty, M.D.
Q. Whenever I try to walk fast, the bone above the ankle in the right leg pains me very much. What might be the reason?
Reason: Tendons connect muscle to bone through fibers. Pulling at these fibers too hard or for too long—or when the muscles haven’t been stretched enough—can cause microscopic tears.
Prevention: Stretching before and after exercise can help prevent or reduce the pain. Also, be sure to wear a well-fitting, supportive athletic shoe with plenty of cushion and a good arch support.

Reason: A stress fracture is a microscopic crack, more common in women, that occurs when the shinbone isn’t strong enough to handle the load the body’s putting on it. Excessive running or even excess weight, for example, can cause a stress fracture.
Treatment: You’ll need rest and bone protection until the crack heals. It’s important that your health-care provider guide you through this process.
Reason 1: Muscles rely on blood to bring in enough oxygen. Activity increases their need. If your legs aren’t getting enough oxygen, you may have a dull, aching calf pain. Atherosclerosis (hardening of the arteries) can cause poor circulation. Diabetics are particularly prone to this condition.
Reason 2: A more rare but also serious possibility is chronic compartment syndrome, which usually occurs in highly trained athletes. Tough yet flexible tissue-envelopes, or fascia, surround leg muscles and divide them into compartments. Extra muscle work and blood flow during exercise increases the pressure in these compartments. But rarely, the pressure gets abnormally high and actually impedes that blood flow. At this point, muscle fibers can die. Pain from chronic compartment syndrome is usually deep, sharp and intense.
Treatment: Your health-care provider can check you for any of these conditions and get you started on a treatment plan. You may need surgery to correct chronic compartment syndrome.
