I'm in my early 20s and had a bad case of tendinitis 2 years ago which left my hands, wrists, and forearms in a horrible state of pain (tingling, soreness, numbness, loss of strength, inflamation). What worked for me was a combination of: - Always maintaining good posture when typing (according to ergonomic guidelines of a computer workspace). Prior to this I had programmed laying down and in all sorts of odd positions on a sofa. - Reading the "How I Cured my RSI Pain" link. I didn't read Sarno's book but what I took away from reviews was that pain is largely psychological. When I stopped constantly thinking of pain, it went away! I know...sounds magical, but it worked! This made a BIG difference. - Exercising daily and doing wrist exercises. What could have possibly worked but I can't verify is: - Switching to Dvorak. Made me type faster and more naturally but I have no idea if it helped me at all. What I definitely know didn't help: - Massages. They temporarily helped to relieve pain in my arms but did nothing to stop pain in the long term. It took a good half year after I made these changes for the pain to start receding. I still have some minor bouts of pain at random times but it seems to come up only when my posture is off and I have been programming for hours and hours without break. Hope this helps!
