I broke my collarbone at the mx track 5 weeks ago right at the outer end of the bone. Xrays showed the bones to be well aligned, so I just wore a sling for 3 weeks. Now at 5 weeks I still feel tension in the whole shoulder and when I do certain moves with the arm upward there is like a stinging pain in my arm, not in the shoulder... I am guessing this isnt the collarbone hurting, but something else that has been stretched or torn? btw. When I crashed and got up to brush myself off I was surprised to find my arm was completely numb for a little while, maybe half a minute. Couldnt move it at all, like when you have slept on the arm and its numb when you wake up... I now have a visible lump on top of the shoulder which I think means the bone has been healing, because the break was about where the lump is. But what might it be that causes the general tension in my shoulder and arm? I also sometimes feel something plop and move in the shoulder when I do certain moves, it isnt the same as when the bone was clicking... Should I excercise the shoulder or do as little as possible with it? It feels pretty good as long as there are no sudden moves or jolts to the shoulder. Im 32 and in pretty good shape btw.
