Hi!
It is difficult to diagnose the cause of pain in the arm on net. Arm pain in can be due to injury, irritation, or inflammation of muscles, ligaments, tendons, bones and joints. So it could be shoulder pain or elbow pain referred to upper arm region or it can be muscle injury. It can also be due to Scalene Myofascial Pain Syndrome, clots in deep veins, inflammation of veins or lymphatics. Do discuss this with your doctor and get yourself examined. Take care!
