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 at rest.
Although it’s sometimes considered a disease, claudication is technically a symptom of the 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.
Claudication symptoms include:
Other symptoms include:
Talk to your doctor if you have pain in your legs or arms when you exercise. If left untreated, claudication and peripheral artery disease can reduce the quality of your life and lead to potentially life-threatening complications. Claudication may limit your ability to participate in social and leisure activities, interfere with work, and make exercise intolerable.
Claudication is most often a symptom of peripheral artery disease. In peripheral artery disease, the arteries that supply blood to your limbs are damaged, usually as a result of atherosclerosis. Atherosclerosis can develop in any of your arteries, especially those in your heart. When atherosclerosis affects your arms and legs, it’s called peripheral artery disease. Atherosclerosis narrows the arteries and makes them stiffer and harder. That’s because the arteries get clogged with clumps of fat, cholesterol and other material, called atherosclerotic plaques. These plaques can make arteries so narrow that less blood can flow through them. You feel pain because your leg muscles are not getting enough oxygenated blood. Oxygen is the fuel that muscles need to contract.
Atherosclerosis isn’t the only possible cause of your symptoms of claudication. Other conditions associated with similar symptoms that need to be considered include spinal stenosis, peripheral neuropathy, certain musculoskeletal conditions and deep venous thrombosis.
The risk factors for claudication are the same as those for developing atherosclerosis, including:
In extreme cases, the circulation in your legs or arms can be so limited that you feel pain even when you aren’t exercising, and your legs or arms might feel cool to the touch. Severe peripheral artery disease can lead to poor healing of skin injuries and ulcers. These cuts and ulcers can develop gangrene and require limb amputation.
You’re likely to start by seeing your family doctor or a general practitioner. However, you may then be referred to a doctor who specializes in disorders of the cardiovascular system or a vascular surgeon.
