My specialist reckons i have a degenerative form of arthritis in both wrists, having checked me out since my right wrist is now giving me probs following the 2 ops on my left.
It's down to busting then both in my 20's & working in a -25C environment for the subsequent next five years. Seems the severe cold harmed the tissue that was damaged & it never recovered properly.

No gaming from now on
Dunno how i'll go on with the mouse, but it's 5 minutes then rest for the next hour. So i get 10 mins per hour using both.

Anyone any ideas??
