Not a solution

[redbird]

Doing a lot more stuff left-handed is helping my shoulder, yes.

But my left hand hurts, from too much typing and mousing (and probably miscellaneous other tasks). It's definitely the hand, and especially the fingers.

Suggestions that do not involve hiding in bed for the next week are welcome.

Around here, craft stores sell these horrid looking orange spandex things that look like fingerless gloves. They are marketed for cross stitchers. I find using them can help my keyboarding and mousing aches and pains quite a bit.

I was going to suggest a tubular support - you can occasionally get them with thumbs so they actually stay on the hands - but this sounds like a better option.
