Crap, yesterday I found out why my wrists are hurting. I have De Quervain's Tenosynovitis or inflammation of the 2 tendons that operate your thumb. I currently have a hard plastic splint on my right thumb/wrist and half way up my arm. I'm to not use my thumb for anything or pick up anything heavy - even my purse! Tomorrow, I see if I get one on the other hand. No sewing for 6 weeks! What will I do?
