I have had more cases of tendonitis than a non-athelete can possibly have. Last year it was my knees and elbows. This year it's my shoulder and both thumbs.

The problem in my thumbs has gotten so bad I have taken to wearing thumb braces. The only braces I find are for the protection and recovery of thumb injuries relating to sports. They are made to protect the thumb from additional injury and are huge, bulky and often uncomfortable, hardly something I want to wear all day long.

So, I have created my own brace manufactured out of a bulky brace and the common carpal tunnel half gloves. This provides enough support of the thumb, yet it fits sleekly over the hand. To me it seems ideal. I've got a prototype, and we're ready to start sewing. As part of my product research I'd like to know, are thumb problems common or uncommon with ms in particular. I'd appreciate any responses to see if there really is a market for this product.
