1. A cramping pain, as a result of exercise and relieved by rest, that is caused by an inadequate blood supply to the affected muscles, usually the calves.
2. Pathological pain and cramp in the calf muscles which is aggravated by walking and caused by an insufficient supply of blood.
3. Pain in the leg muscles which occurs during exercise and is relieved by rest.

Intermittent, means coming and going at intervals, and claudication refers to limping.

This term was originally described in horses which went lame with exercise and then recovered with rest.

The Roman Emperor Claudius, who ruled from A.D. 41 to 54, is said to have received this name because he limped, presumably from a birth defect; and he also stammered.

Pain and paresthesia (abnormal skin sensations), often succeeded by sensory loss, motor weakness, and loss of the reflexes, arising in the motor and sensory distribution of lumbar or sacral roots after the patient has walked some distance.

The neurologic signs, which are sometimes minimal but are accentuated by walking, are those of a cauda equina syndrome or a dull pain in the lower back and upper buttock region, analgesia in the buttocks, genitalia (or thigh), accompanied by a disturbance of bowel and bladder function.
