I have carpal tunnel syndrome in my right hand also my left hand but worse in the right than left, I had to go to the hospital a while back & they wired my hand( hands ) up to some sort of electric gizmo - the doctor was surprised the amount he cranked up into my right hand, I walked away from the operation when he said they go through your wrist ( whilst awake ) don’t fancy it tbh 
Some days worse than others I think it was at its worse the day of the big meet to not realise I was using the wrong controller
