I was going over a jump on my skis about 10 days ago and when I landed I sorta fell forward and went onto my shoulder. The shoulder felt like it was out of place so I went to a chiropractor and he put everything back right so it felt like my shoulder wasn't pulling on my next. However the next morning when I woke up it felt like my collar bone wasn't sitting correctly where it connects to the sternum and I was able to pop it back into place by putting my arm down by my side and tensing all my shoulder muscles. I still have to pop it back into place every morning when I wake up but it seems to be happening less often after the first couple of days. I guess I could see a doctor, but they never seem to have anything they can do for you, especially since this isn't sore at all. The chiropractor did help it, but it popped back out again.
