I'm 20 years old and have had my shoulder reconstructed twice. Football injuries. every day is a battle in the gym with pain. I have arthrities in both of them now. Being so young this really sucks. So I can tell any one out there with shoulder pain to not mess around get it checked out, take a break, any thing to take care of them. I now can train heavy and manage the pain easily but the doc told me if I had waited just a couple years I would be imobile in my right shoulder by the time i was thirty. Brothers and sisters take care of your shoulders because it is not a good feeling to have your girlfriend put your shirt on for you.
