It was kind of an experiment and it confirmed what I have suspected. It's mostly the computer, typing and mousing and maybe not so much the knitting although when I'm already sore that could exacerbate it. (Hey, I just spelled exacerbate correctly without the spell checker!)
So just this short post with none of my usual add-ons. I'll be cutting way down on my computer time and when I do get on, setting a timer for 10-15 minutes so I'll GET OFF ALREADY! And I'll limit it to only a couple of times a day. Lately, I tend to write posts in spurts so no big change there.
