Hi Ryan, Traci, MMW, Majr Tom, Jessica, and emef,
There is certainly a name for what you all are experiencing and any doctor that tell you not to worry about it should be ashamned. It is certainly something to worry about. Although, I don't have the answer as to what it is...however, try doing a search by typing in pain in collar bone and see what comes up. Someone, somewhere know the name of this pain and has an answer for you. Don't give up as you can see you are not along here. You may also want to contact a chiropractor, certainly couldnn't hurt right. Hope this helps somewhat.
Good Luck
Faded Rose
