Yeah, I definitely get the pain part. Actually, I should be pretty thankful because it's my aversion to handwriting that made me spend a lot of time on the computer, leading to my entire career. :)
FYI, writing caused me pain if I did it for more than a line or two, and was always a slow and laborious process. It turned out I'm predisposed to RSI -- a load of vitamin B6 plus learning to write cursive italic, plus switching to fountain pens really improved my writing and eliminated the pain.
