What is "intermittent claudication"

n. lameness due to pain in leg muscles because the blood supply is inadequate; pain subsides with rest

Intermittent claudication (Latin: claudicatio intermittens) is a symptom that describes muscle pain (ache, cramp, numbness or sense of fatigue), classically in the calf muscle, which occurs during exercise, such as walking, and is relieved by a short period of rest. It is classically associated with early-stage peripheral artery disease, and can progress to critical limb ischemia unless treated or risk factors are modified.

Claudication derives from the Latin verb claudicare, "to limp".
