I've had pain at the top of my right arm for months now - any idea what it could be? I thought it was a muscle strain but it comes & goes now with no apparent pattern. It does make it very painful reaching around behind me to pick things up! Any ideas??
I know I should make an appointment with GP but it seems so trivial to waste her time (but as it's been months now, seems like I need to do something!). TIA.
