Sharp throbbing pain inside my collar bone?
I've had this for almost as long as I can remember (I'm 29). Very occasionally, I get an extremely sharp throbbing pain in my left collar bone. It will go as fast as it comes, for no explained reason. The pain can be debilitating at times to where I have to pull the car over, if I'm driving, until it subsides. Usually though, I just get these intense throbs for 30 seconds or less.
I've always been pretty healthy w/ no collar bone injuries. Any idea what this is?
