The thumb saga continues....
I went to the doc's today and he says I've pulled a muscle in my thumb too as well as the sprained ligament, and that's why it's not getting better. It's a muscle that is in the pad of the thumb and attaches to the bottom bone. That would explain the swelling then
It is actually hurting to stitch now, so I'm getting a max of two hours a day, if that. I have to rest it again for 10 days and take some really strong pills, and then things will be sorted.
