Molly, that's exactly where Brian has the worst of this pain, root of thumb into wrist. I don't want him to have more cortisone shots at this point. He's had two this year already (3 if you count the one where the doctor missed the mark). Enough is enough, already.
It's frustrating for him, as I know you can imagine, as he's a fitness buff and weight training is a big part of that. To finally have his elbow, shoulder and legs at full efficiency, only to be bit in the butt by this and still be unable to do his programme properly is maddening for him.
At least the docs are listening to him now. Small mercies add up, you know.

Many hugs,
