Upper Left back "pain", help?

i also suffer from a numb sensation in the shoulder, it also happens , would you believe, to my head and face. after xrays ultrasounds blood tests etc., it turned out the cartlidge between two 2 discs in my neck has all but worn away. when i am stressed it is worse, so dr. said learn to de-sress, (easier said than done.)i do not experience pain though, just the numbness.i take a1500mg glucosamine tablet once a day (available at health stores and chemists) and swear it has helped. another thing i was told to do by a sports trainer,is to lay in a hot bath to which you add a packet of epsom salts, when you get out you have someone mage the area with oil of wintergreen, also from the chemist, i'm not so sure if it really helps but it sure feels good !! maybe sitting at the computer all day has left you with some pressure on the nerves. if you can reach the area with your hand try gently kneading it for a minute or so a couple of times during the course of the day.how ever it goes i wish you well and hope somewhere along the way you get the right advice. hooroo.
