Firstly, I would like to state that for my job, I use the computer at least 8 hours a day, a lot of mouse usage with the right hand and I'm a right-handed player. I often notice when I first start a match, and especially on the serve, I get this wicked pain on the front of my hand, not the palm, just above the wrist and below the knuckles. It's not the wrist itself. It makes it hard to really snap on the serve and then on forehand ground strokes there is pain as well which can make me tentative. It often gets better as the match goes on, but it can take a half hour or more and it doesn't help out my starts in matches. Does anyone know if too much mouse usage can do this to your hand? Should I switch to left-handed mouse usage? Anyone ever have this and have any tips to alleviate the pain? Thanks!
