Hurt arm from baseball?

so i was getting ready to pitch the other day,when all of the sudden a click went off in my shoulder.my friends dad is a doctor and he said i might have pulled or partially tore a muscle near my rotator cuff.i iced it to see if it got better,and i have a stinging in my shoulder,and near my hand it stings also which I don't know why?!shoulder I get this checked out,i have about 2-3 months off now,what should I do?
