I had a serious case of RSI when I was putting together my University final year project and inserting screenshots into the documentation. Excessive mouse use cutting & pasting! It was most painful when trying to get to sleep at night or when it was exposed to heat. Constant sharp tingling. A long period of rest was the most effective. Ensuring your wrist isn't at funny angles, at any point during the day - esp if you still need to type daily. It's also a good idea to avoid resting on your elbow when bent as associated nerves are exposed.. I also had a swelling at the wrist joint that remained even after the tingling had gone. I found that this only went away when I started doing light punchbag work after several months of rest. No lasting issues and I'm at a computer for 10+ hours a day.
