Up to half of patients don't have any symptoms, but others feel pain when they walk or exercise, a condition known as claudication.

One symptom called "intermittent claudication" occurs when pain develops in the calf, thigh or buttock muscles after walking short distances and subsides after rest.

Cilostazol, also sold as Ekistol, is used for treatment of intermittent claudication, or limping, usually as a result of arterial disease.

The treatment of intermittent claudication is the treatment of arteriosclerosis in general.

The patient is liable to sudden attacks of numbness, tingling and weakness of the limbs which pass off with rest—intermittent claudication.
