Im a 14 year old girl that plays soccer. A couple years ago i fell awkwardly on my shoulder only to find out that I had torn my rotator cuff which caused tendinitis. It was fine for a while with some pain now and then. But as i started playing soccer and/or running in the cold my shoulder swells up and I have a very very sharp pain. It even hurts to breath. I love playing in the cold, but the pain is sometimes to much to bear. If anybody could give me tips or tricks to prevent this pain from coming or at least so i don't have as much pain, it would be greatly appreciated. Again thanks
