I'm fairly young(30) and in decent shape.. Anyway, I played basketball for a couple hours about a week ago, which I do pretty regular.. Anyway, the next morning, my shoulder/collar bone area was sore and it hurt to put weight on it. It stayed sore for a few days but then went away. No big deal I thought..

Well... today I went to my first 3-D shoot of the year and I had not shot my bow since the injury.. When I first pulled the bow back I could not believe the pain! I was absolutely unable to hold at full draw... Its not really my shoulder, but more between the shoulder and the collar bone...
This is the first problems I've ever had with shoulders... Any ideas of what the problem may be?
