This is a little topical for me, though it's not back or neck pain I have. I've been struggling with a sore shoulder for a couple of months. Thought I'd pulled something, and it'd go away on its own, but no joy. Went to the physio who's given me dumb little exercises to do (though I think they are helping.) Basically, if you're taking time to keep your back and neck limber, don't neglect your drawing arm either (see Tiana's post above). Even just swinging and rotating your arms a half dozen times every hour or so will help to keep your shoulder loose, and avoid pain!

I started on a map for the October challenge, but had to give up as I felt it was making my shoulder worse. I use a computer all day in my job and can't avoid that, but felt I needed to give myself a break in the evenings. I might try and finish at some point down the line.... or it may join that giant pile of unfinished maps that I have! *cries*
