Just a suggestion: I had carpal tunnel surgery on both wrists 10-12 yrs. ago. My hand and fingers had made it this far..... but,
Am wearing nighttime wrist hand braces each night. This is my way of resting my hands, fingers, wrists at night.
The surgeon friend that did my surgery mentioned to me that one's hands/wrists 'got in more trouble' during the night than daytime.
He also stated that you build up adhesion/scars inside where operation done and the more you do surgery on the carpal tunnel area the more it will be impeded by scar tissue....makes sense that he suggested I routinely use hand/wrist braces after day of using my hands a lot.
You might want to just go in CVS (where I get mine, other places sale them) and try a one on and see how your hand/wrist feels. Mine are made by Futuro for R and L wrists.
Trust you soon get some relief....it hurts so much... I recently had a flare for a month and both of my hands/wrists hurt with elbows and shoulders. Got steroid shot in R shoulder to help reduce swelling and allow me to use my R hand. I'm like you I have glass plates and have had them for 50 yrs. Yes, I'm a senior and I'd like to finish out life using my original day china!
