What are the symptoms of intermittent claudication?

Pain in leg: When a muscle group does not receive enough blood flow and oxygen due to a blockage in the circulation, that muscle group will release Lactic Acid which is the cause of the pain. Rest will stop the pain and resuming physical activity will recreate the pain in a very consistent fashion.

Crampy leg pain: Claudication, derived from a latin word that means "to limp, " is characterized by pain in the leg muscles. It is caused by blockages in leg arteries depriving the blood supply needed for activities like walking. Resting, or stopping, relieves the pain because less oxygen is needed at rest. "intermittent" refers to the timing of pain: "it hurts upon walking but gone upon stopping, like clockwork.".
