Sore hands

I seem to have perpetually sore hands. My wrists have always bothered me with the guitar, but now my knuckles are trouble too.

The latter seems to have started when I overdid the rock climbing...which I stopped. Stretching out my wrists seems to help the first some, but I'm convinced now that they're just the price of doing business, that my fate is to have sore hands. C'est la vie.
