Had that on my thumb.
Surgery fixed it.
Good luck.

I saw a fellow taking a picture of an electrical tower from about two miles away. It was nighttime and his flash went off. I didn't say anything to him. Then he turns and takes a picture of the full moon. Again the flash goes off. I said to him, "I don't think your flash will help you with that." He turns to me and said, "Couldn't hurt."
