I have been working out hard for 9 months. I have put on 30lbs of muscle. I just started throwing a baseball the otherday to get warmed up for the season. when i did this i got a sharp shooting pain on the outer side of my forearm. I know that i really havent been steching enough so i am sure this has had something to do with it but is there anything that i might be able to do to make this go away?
