When at rest if I lay on my left shoulder pain seems to radiate don my arm to the elbow. And in turn to my wrist. It seems to come from my shoulder like it is hyperextended and causes un fathomable pain and discomfort. This in turn hurts my elbow or the tendons that surround my elbow and proceed down to my wrist and my hand . Sometimes it starts in my wrist after using my I pad and I phone. But the pain is throughout the arm . Please help
