My shoulder is swollen. I play softball, I have since I was 3. I had a collision at home plate because I am a catcher but I don't know if that's how it happened. I noticed some pain a couple of weeks ago and showed mom and she noticed it was swollen pretty bad. It often hurts so bad y thumb hurts and whole arm goes numb... I can't lift it over my head or straight out any direction.. I have a doctors appointment next week but wanted to ask to get and idea of what it could be
