@zipperlip When my right wrist plays up, I'm right handed, I switch the computer mouse to the left hand for a couple days . It's difficult at first but gives the right carpel tunnel a rest and I believe doing this is also very good for the brain.
I wear a strap just below the elbow when required for tennis elbow, it take pressure off the tendons.
I go in for a TKR, total knee replacement ( revision ) next month, the 3rd on the left side ???
apart from that, I'm sweet. I'm 70 and many old mates are long gone.
