My hand hurts

Last year with six weeks of digging, including hours upon hours of pottery washing, I was fine and healthy. This year, 2 weeks into the dig, I've injured my [right] hand. I have no clue what I did to it, but it hurts to do anything. I thought that over the weekend it would feel better if I rested it, which I did, but to no avail. For brief periods of time it was ok, but as soon as I used it it would hurt. And I can't not use my right hand. I can't "take it easy." My left hand is good for only basic things, such as carrying things that aren't fragile, or liquid for that matter, typing on that half of the keyboard, holding things as I do whatever needs to be done with my right hand. My left hand has limited motion. Most people have a dominant hand, but at least can do some things with their non-dominant hand. I'm not most people, though.

So even if I were to stop digging, I'd have to stop eating, getting dressed, grooming myself, opening things, etc., if I were to completely try to stay off of my hand. That's not happening, because I refuse to be helpless. I can still use my hand, it just hurts a lot. Hopefully the non-archaeological stuff isn't hurting it...

I've given up knitting and crocheting until I get treatment or get better, whichever comes first. Or maybe just for the duration of the dig. I don't know what I'll do about my summer job if I'm not better when I get to the States. I'm supposed to teach knitting, crocheting, and crafts!!!!!!

How did I do this to myself? Was it the turiyahing? Was it the bucket carrying? Was it the balk-trimming?

And what would you do in my situation?
