I've been boxiing, and now my right shoulder hurts badly. It seems to be in the joint. also some of the muscles also hurt. I don't know if i have torn something, or what not. I just need someone to tell me what to do about it. Should I just keep boxing, lifting, etc, or should I simply let it rest. What about ice packs for these sorts of injuries. Please help me. I can't train as hard as i want to because of this, and it's very upsetting.
