Have you had any injections Into the area? I had two lots that gave me a lot of relief.
I have a numb area across my back from the damage to my thoracic discs.
I got that injury in 2003 just before I had a nasty car accident.
It supposed to be a difficult area to treat surgically. I don't fancy complications from that high up, so unless it was life of death I wouldn't entertain it.
I think we all get feelings of vulnerability after injuries. As long as you take steps to keep the muscles working well then you should find it gets real support.
