You can buy finger splints at walmart...they are really hard to find...come in a teeny little box in the section where they sell band-aids and foot cushions...if you wear them at night and whenever you can, they will help rest the tendons in your thumbs...it took a good 4 months for me, but they were the only thing that helped...they are just a piece of soft metal lined with foam, they are easy to adjust to the shape of your thrumb...I had to tape around mine because they kept slipping off...but they did work.
