5. Claudication
Claudication is leg or arm pain that occurs during exercise. It’s caused by too little blood flow. It is often a symptom of arteriosclerosis (hardening of the arteries) or peripheral artery disease. Symptoms start with pain during exercise, followed by pain at rest. Toes and fingers may turn blue or be cold to the touch.
If you have any of these symptoms, contact your doctor. Risk factors include smoking, high cholesterol or blood pressure, obesity, and diabetes. There may also be a familial connection.
