As we use computer more frequently than exercise these days, we need to know more about RSI.
Sometimes I have the syptom of RSI causing not only from computer use, but also from play sports.
I have been aware the problem and also correct them. Following is a list of what I experienced:
1. My knee lost power suddenly when walking.
2. My right index finger tingle.
3. My back hurts.
4. My shoulders tighten up during sleep or after waking up.
5. My right elbows causes pain.
Again, I did not know about RSI before, but I was lucky that I was able to correct them before it becomes severe. See a doctor if you experience such problems. You may also read something about it here: http://www.rsi.deas.harvard.edu/
