For some reason dating back to my childhood my right arm always hurts when it in just by my side. I feel this sharp pain between the joints of my shoulder and I haven't been able to figure out the problem. The only way that I have been able to get some sort of relief is to have my arm above my head... somewhat resting on top of my head. I have tried stretching my arm every angle I can get it to go but it only provides temporary relief. Has anyone ever heard of this and/or do you have any suggestions as to how to overcome this.
