Mine started in my spine when I was around 13 and by the time I was in my 20’s it showed up in my hands and wrists. Of course, now its all joints. The worst part is the chronic bursitis that comes along with it.
I try to crochet every day, or knit, or even type, as long as all my fingers are in use, but if I take a break from it for a few days, or do something I’m not used to like kneading bread, it’s excruciating until I get back to crocheting again.
So now you know — crochet/crafty stuff is therapy!
Huh.
