Well, there is a medical problem known as claudication which causes pain the the legs on exertion-
usually when walking.

What is claudication?
Claudication is pain in the calf or thigh muscle that occurs after you have walked a certain
distance, such as a block or two. The pain stops after you rest for a while. Each time the pain
occurs, it takes about the same amount of time for the pain to go away after you stop walking. If
you notice pain in your legs after you walk a block or more, you may have claudication.
What causes claudication?
Claudication occurs because not enough blood is flowing to a muscle. The artery that normally
supplies blood to the muscle gets narrow, and less blood can flow through the artery. When
you're resting, enough blood flows to the muscle to meet the needs of the muscle. However, when
you exercise (walk), the working muscle needs more blood and the narrowed artery may not let
enough through.
What causes the arteries to narrow?
Atherosclerosis causes the arteries in the legs to become narrow. With atherosclerosis, fatty
material builds up in the walls of the artery. This fatty material causes narrowing of the artery.
Health conditions such as high blood pressure, diabetes, high cholesterol and cigarette smoking may
cause you to have atherosclerosis.
Who is at risk of getting claudication?
Risk factors for claudication include high blood pressure, diabetes, high cholesterol, cigarette
smoking and older age. Claudication is also more likely in people who already have atherosclerosis
in other arteries in the body, such as the arteries in the heart or brain. People with claudication
may have had a heart attack or stroke.
How does my doctor know I have claudication?
Your doctor will check the pulses in the arteries in your legs. He or she may use a stethoscope
to listen to the sound of your blood going through your arteries. Your doctor may hear a noise in
an artery, called a bruit, which may be a warning to your doctor that there is a narrow area in
the artery.
Are special tests helpful?
Your doctor may order a test to check the blood flow in your leg. This test is often performed in a
hospital lab.
The test for checking the blood flow in your legs is called a Doppler study. With this test, blood
pressure cuffs are wrapped around your arm and your leg on the same side. The kind of cuff put on
your leg is the same kind of cuff that's wrapped around your arm when your blood pressure is
measured. Four cuffs are wrapped around your leg--one at the upper thigh, one at the lower thigh,
one at the upper calf and one at the ankle--to measure the blood pressure from the top of your leg
to your ankle. A cuff is also wrapped around your upper arm to measure the blood pressure in your
arm. The blood pressure in your arm is compared with the blood pressures in your leg. A drop in the
blood pressure in your leg may mean narrowing of an artery.
What other tests might be done?
If surgery might help treat the symptoms of claudication, your doctor may recommend an
arteriography. This is an x-ray taken after dye is put into an artery. The dye study may show
narrowing in an artery and provides a "map" for the surgeon who will do the surgery.
Can anything be done to treat the symptoms of claudication?
Yes. There are 3 steps in treatment. First, change your lifestyle to reduce risk factors for
claudication. If you smoke, it's very important to stop. It's also important to lower your
cholesterol level and blood sugar level (if you have diabetes).
An exercise program, such as walking or stair climbing, is also helpful. Begin exercising slowly and
gradually increase the time you spend exercising. You may see improvement in your symptoms within 2
months. To begin an exercise program, exercise each day for 30 to 60 minutes. If claudication (pain
in your legs) occurs while you're exercising, stop and rest until the pain is gone, and then start
to exercise again.
Can medicine help claudication?
Pentoxifylline (brand name: Trental) or cilostazol (brand name: Pletal) may help your claudication.
Your doctor can tell you which one is right for you.
