What is the difference between a “Charlie horse” and pain from intermittent claudication?
A. Pain from intermittent claudication is caused by your leg muscles not receiving the oxygen rich blood they require during exercise. The pain can be severe enough to hinder a person from walking. A “Charlie horse” is a leg cramp in the muscle and can normally be relieved by rubbing or massaging, and this may occur at rest or merely with stretching. The pain from intermittent claudication will always subside upon resting. If you are not sure if you have PAD, see your doctor!
