For the past 3 days, I have been having pain in my upper right arm. It has been throbbing, and feels as if i got a large shot, when touched it feels like bruised but not on the skin but deep in the tissue. Prior to this pain, I had been suffering from headaches nearly everyday, and recently I have been getting this exact throbbing pain in my upper right side of my back, however it occurs every once and a while. Ive also experience sharp pain in my fingers.
