Mild thread hijack since PTs & wrists are being discussed in here... I've had tendonitis or something in my right wrist for years. I've gotten all my bikes adjusted so that I can ride without my hand going numb. I had my wrists checked last year for carpal tunnel by EMG - no carpal tunnel showed. I'm usually very careful about keeping my wrist position neutral no matter what I do. Whenever I go to a doctor, I get either told carpal tunnel or tendonitis - and there's no getting someone back who has already decided wrist pain + sometimes numbness = carpal tunnel.
But all of a sudden this year (and this may be entirely unrelated to all the issues I've had with the right wrist), my right hand has been going numb paddling - it starts off with the thumb going numb, and the tips of the middle & 3rd fingers... and then progresses to the entire hand. Using a smaller paddle blade helps, but it still goes numb. I just spent entirely too much on a paddle with an oblong shaft that it takes about 10-15 miles before I start getting the numbness in the thumb & other fingertips and the numbness doesn't progress much beyond that... Which is a huge improvement. I've had several people that teach kayaking, race, whatever look at me while paddling to try to figure out if I'm doing anything wrong - my wrist is definitely neutral while paddling, and I open my hand/fingers when pushing the blade away from me - so I don't have a death grip and I'm constantly opening and closing my hand. Someone suggested more torso rotation would help...
Any other suggestions?
