Start learning to use your hand that you don't favor the most ! After i had my tunnel release surgery it was an immediate effect on your daily life especially if you are a daily computer user , it took me a good month and a half to teach my left hand to navigate with the mouse, what a major struggle it was , i have also seen arm braces at some ergo outlets that can attach to your desktop so the base of the palm of your hand doesn't get as strained by the weight of your arm , the brace is supported at the forearm , i haven't gone that far yet , but seriously that Web wheel truly works give it a try ! Or it may be time for a couple corticosteroid shots , i used to get them until they no longer worked.
