I've got a bit of a problem.

I have this reoccurring blister on my right thumb. Both knitting and crocheting aggravate it so I haven't been able to do either one for a week at least. The blister comes to the surface, peels, new skin forms, and then I get about 2 days where it feels healed up and it starts all over again. I had a Dr. look at it about 3 months ago and he said he didn't know what was causing it and to wait and see. So I have to focus on what I can do instead. Which is sewing for one thing. But today it was 97 degrees and my fan died, so I didn't get a whole lot of anything done.
