PAD (pronounced P-A-D) is the result of atherosclerosis – plaque that forms in arteries and blocks blood flow. When blood flow is restricted to the legs or, less often, the arms, the result is PAD. The classic symptom, Aday said, is leg pain that comes on while walking and is relieved with a little rest. On the patient side, Aday said people need to understand that leg pain or needing to spend more time sitting isn’t always just part of aging. There needs to be a further explanation than just, ‘Well you’re getting older.’”Source: American Heart Association.
