I was trying to reach something on the back seat of my car, and overstretched, tearing the rotator cuff muscle (according to my GP)in my left arm. This was in January. I have had a steroid injection into the joint, am on pain killers, topical and oral and am still in pain with this. I get a stabbing pain from a particular point in my bicep(?), not continual. When I jerk my arm for any reason, eg holding my sons hand and he tugs it, flick my hair over my shoulder, that sort of movement, the pain is unbearable. It runs from the front of my shoulder, all down the muscle in my arm, mainly on the inside of my arm, to my fingers, and is a very sharp pain, much like the one you get when you pull a muscle in the first place! I also have tennis elbow due to misuse of my arm because of the pain and limited movement! My GP has referred me for physio, but the waiting list is 12 weeks, and I just don't think I can wait that long. The only way I can sleep is by lying on my side and resting my arm on a pillow, and taking pain killers before I go to bed. Help!! My husband thinks wearing a sling to immobilise my arm and shoulder might be a good idea. Should I go back to the GP yet again about this?
