So my left arm hurts in the exact same spot you would have an injection and it feels exactly the same way. It really hurts and has come and gone thru the day. Its spreading down my arm and feels like an ache in my wrist. I dont want to go to the doctor or the hospital plus getting a gp appointment at the moment is practically impossible. I've not damaged it in anyway and it started last night as I was getting into bed. It actually is starting to really hurt now and im not usually bothered by pain. Anyone got any suggestions?
