Sit on chair, feet flat on the floor, forearms on top of your thighs, palms facing up, hands overhanging your knees.
Get a dumbell, do wrist curls keeping your forearms in contact with your thighs. Do 3 sets of 10 reps. Increase the weight as your wrists get stronger.
Amazingly, the symptoms just gradually go away in a few weeks.
I was bothered for years with carpal tunnel until I was shown that. If I stop exercising my wrists it takes about 6 months before the symptoms recur.
