Thanks guys, very helpful.
tinytim, I’ve tried splints and noticed very little difference, I’ve had 2 injections in each wrist, which helped. There still seems to be some deterioration.
FB-ATB, I go to an osteopath, and worked through some of that. Might go back after a nerve test and see if that will pin point the problem.
I’ve had some swelling in my left thumb in the last fortnight too, so I’m off to the GP to get the ball rolling, certainly some more testing anyway.
