DefinitionBy Mayo Clinic Staff
Claudication is pain caused by too little blood flow, usually during exercise. Sometimes called intermittent claudication, this condition generally affects the blood vessels in the legs, but claudication can affect the arms, too.
At first, you'll probably notice the pain only when you're exercising, but as claudication worsens, the pain may affect you even when you're at rest.
Although it's sometimes considered a disease, claudication is technically a symptom of a disease. Most often, claudication is a symptom of peripheral artery disease, a potentially serious but treatable circulation problem in which the vessels that supply blood flow to your legs or arms are narrowed.
Fortunately, with treatment, you may be able to maintain an active lifestyle without pain.
