I was starting to get wrist pain in my right hand at the end of the day. I believed it was from never learning to type properly, I only used two fingers on my right hand even though I could type relatively fast.
I tried many times to re-train myself to type properly, but with proper technique I was only typing at half of my normal speed and would give up quickly.
In the end I switched to colemak to force myself to re-learn how to type with proper hand technique. It took a year but now I can type faster than I used to be able to with QWERTY and without any pain. It was definitely worth it for me, but there are enough annoyances with everything being QWERTY by default that I wouldn't recommend anyone make the switch without a reason to do so.
I had the same experience switching to Dvorak. It forced me to relearn how to type, and when I was relearning, I made sure to learn properly. The switch, and relearning to type, 95% solved my RSI problems.
