There are certain angles, positions, and forces that cause me to feel the plate, but its rare and not painfull. If they cut you again to remove it, the numbness returns and you start all over. You know whats funny, if I flex a certain way, like a forward shoulder shrug, I can really see the calvicles clearly. The right plated one is twice the thickness of the left, not just the added thickness of the plate which is only a few mm. The rest must be new bone and/or scar tissue.
Almost forgot, swimming is very good too.
