Some people mistakenly think leg pain is a natural part of getting older. But you might be surprised to learn leg pain which develops during exercise and goes away only with rest can be caused by intermittent claudication (IC). This condition is more common in people with diabetes -- who have a two to fourfold increased risk of developing this problem.
Intermittent claudication is a symptom of hardening of the arteries (peripheral arterial disease) and often causes pain in the legs, which can greatly reduce a person’s ability to walk. The pain of intermittent claudication has three characteristics:
- It is a cramping pain in the legs or buttocks during exercise.
- Leg cramps subsides within 10 minutes of resting.
- It’s almost always occurs after having walked the same distance. (However, the pain may occur earlier if you walk uphill or faster.)
Intermittent claudication can be confused with arthritis of the spine, herniated disk, and other diseases of the spine which can pinch the nerves that supply the legs. But they normally do not reflect the same three characteristics listed above.
WHAT CAUSES INTERMITTENT CLAUDICATION?
Intermittent claudication is a syndrome caused by inadequate blood supply, primarily due to atherosclerosis. Atherosclerosis, a condition that involves fatty build-up and the narrowing of arteries, limits blood flow. Cigarette smoking is the most important risk factor for vascular disease. Others include diabetes, high blood pressure, high cholesterol, excess weight, lack of exercise, and a family history of blood circulation problems. People with diabetes should know about the problems that involve inadequate blood flow to the lower body. Inadequate blood flow to the lower legs may result in deformed toenails, hair loss, skin thinning, and ulcers or infections on the feet or ankles. Small cuts and wounds on the lower legs may heal very slowly; thus foot care is an important part of treatment. This is why it’s important for people with diabetes to check their feet every day and visit a foot doctor regularly.
TREATMENT:
First line treatment is used in people who experience symptoms only upon exertion. In these cases, lifestyle changes are key; stopping smoking is critical. Blood pressure, cholesterol and lipids, and blood sugar (in people with diabetes) should be lowered and monitored closely. Another important lifestyle change is exercise. A walking exercise program as a treatment for claudication has been recommended for many years. Studies have shown that exercising can increase waling distance and lessen pain. Also, medications can be used to improve blood circulation and mobility. As a last resort, minor surgical procedures may be performed to help restore blood flow in people whose arteries are blocked. So, if you are combating leg pain, discuss your symptoms with your doctor. It just may help you take that next step.
