my doctor has prescribed Butrans skin patch. My current medications include Amlodipine, Atorvastatin and Atenolol, Will any of these cause a problem? Also I currently use a magic pad, heated in the microwave and applied to my knee for 20 minutes for occasional pain. Will this still be permissible?, and 3. I currently have a 20 to 30 min whirlpool bath each week. Is this compatible with the patch? YYYY@YYYY
