Hello Dr. Mark, I broke my collar bone in mid-November of 06. I had surgery on it a couple months later, they put a plate and some screws in there to hold the two broken ends together. Fairly simple surgery and everything turned out fine and it had felt good up until about a month ago. For the last month, at least once a day (most times more) my shoulder and collar bone area goes completely numb. Have you heard of this, what do you think?
