Wrist pain has nothing to do with Carpal Tunnel Syndrome. Carpal tunnel would result in compression of the median nerve, with numbness/tingling in your thumb, index and 1/2 of your middle finger. Most likely your wrist pain is just that....an overuse type injury. I would suggest a control panel at a comfortable height (if you are too tall over it you have to extend your wrists too much and that will cause pain) and adequate shelf space between your joysticks and the end of the control panel so your wrists can rest. Another idea is to fully stretch and extend your wrist and fingers prior to lengthy gaming sessions. Bananas (I assume you're thinking of potassium replacement) won't do anything to help you. Hydration MAY help but not likely to be noticeable. If you are having carpal tunnel symptoms (numbness, tingling) I have a hard time correlating it to an arcade machine...more likely cause would be time on the computer keyboard. Medical causes that predispose a person to carpal tunnel syndrome include hypothyroidism and pregnancy. I'm assuming you're neither. Hope that helps.
