Peripheral Arterial Disease

Symptoms include intermittent claudication, or momentary limping because of pain. For example, when a patient with a blockage in his leg walks 100 metres, he starts developing pain in the calf muscle of the affected leg. He stops and rest for a few minutes; the pain goes away and he can go another 100 metres before it comes on again.

In the most extreme cases, if left unchecked, it can cause ulcers, gangrene, and amputation.
