Suggest Treatment For Constant Achy Pain On Legs

My husband has constant aching pain in his legs. He is in excellent shape, not overweight, does not have any visible vein problems. He exercises regularly with walking, bicycling, yoga and stretching. The pain seems to be worse after he has been walking. He does have restless legs as well. He does have arthritis in his shoulders, and his back, and the only medication he takes is Advil. What kind of MD should he see, a Vascular Surgeon? The other Vascular MDs listed seem to be associated with removal of spider and varicose veins. My name is Mary Beth Ryan, and email is: YYYY@YYYY
