Shoulder Pain

I have had ever increasing shoulder pain for a while now. It's really been a problem for my surfing, especially when I'm trying to hang onto my board in a turtle roll. Anyway, I think I finally found a remedy/strengthening solution. For anyone else suffering from shoulder pain this might help (check your shoulder out with a doctor of course). I can hang from a bar with my feet off the ground without pain. My grip starts to weaken after about a minute. If you try hanging from a bar and feel pain, then I'd talk to a doctor before going any further with this stretching/exercise technique. Hope it helps.
