Suggest Treatment For Tenderness In Rotator Cuff

I recently had a gym injury durring the bench press. I think I may have injured my rotator cuff, it was sore for about 1 week. i took some ASA+Robaxin for two days which helped with the pain and swelling. Now my pain is 90% gone but still some tunderness. Just wanted to know if its minor or I should see my family doc.
