When I do chest day after like the first exercise the end my collarbonenear my shoulder starts to pop and hurt alot. It's like a sharp pain but not too sharp to really cringe. I thought it was a shoulder problem at first but it doesnt hurt on shoulder day, and it probably would when the delt contracts if its shoulder. This has been goin on for like many years and i got it checked and he said that there was nothing wrong he could see. But clearly something is wrong or it wouldnt hurt and pop. Anyone have any idea what this could be, my theory is that the end of my clavicle is subluxing.
