Bro, dont think worse case scenario just yet. If you can not abduct your shoulder it may just be an impingement that can be taken care of with rest and antiinflamatories.A good test for a rotator cuff injury is to to put your hand of the affected arm on the opposite shoulder. After that, have sombody else push gently down on your arm and then raise it back up. If this causes pain then you may have a tear. If not, the best medication for impingement that we give to our patients is probably going to be VIOXX. See if you can get some of that. It comes in 12.5 and 25mg. You want the 25mg. Take 50mg for the first three days, one time per day, and then take 25mg a day for about another three weeks and you should feel much better. Let me know if I can help out.
