I too suffer with the thumb pain and especially if I get on a roll with my knitting and don't want to put it down and rest my thumbs. My son brought me a little ball that looks like a brain to squeeze when the thumbs get to aching and I sit and squeeze that for a few minutes, use ice to take down the inflammation. I have lupus and all of my joints act up severely when I have a "flare", wonder if and ice bath would help that inflammation???? LOL Don't think I could stand that!
