I hate that for you. My thumbs are been acheing also. Right in the joint. My dr. said if they keep it up, I would have to go to another dr. and get shots in them. I'm suppose to wear those sleeve things that go on your hand and up your arm. I had been wearing them. But haven't been wearing them. It's hard to craft with them on. Hopefully your thumbs will be better by them getting a rest for six weeks.
