I have been suffering from recurrent bouts of shoulder pain in my right shoulder for the last eight years - the most recent being what I think is tendonitis.There have been several flare ups around my right shoulder and arm, and each time the pain signature has been very different. It first started out as bursitis which never really recovered, then doing some painting work I really damaged - tore ? - something in my shoulder, and this last time I had a warm then burning white hot pain in the front of my shoulder. It seemed to come on without obvious overuse or injury. I could barely move my arm in any direction and the pain developed into what felt like a red hot string. Sleeping was impossible and normal mobility became severely restricted because of pain in movement of any kind.
