I have yet another diagnosis - this time it's CMPS. I wonder if anyone else knows anything about this, or is it yet another WHACBTMKYQFAW (WE HAVEN'T A CLUE BUT THIS MAY KEEP YOU QUIET FOR A WHILE). Have had my first ultra sound guided steroid injection with no effect other than to aggravate the pain, so much so as to herald the return of my screeching in agony every time I move my torso. This is a setback of about 2 years. Oh dear.
