Salt

A table spoon full of sea salt.

No, I'm not going to cook anything with that much salt. No, my hands and wrists disagree about typing eight hours a day and I was told a wrap dipped in water with some sea salt diluted in it worn around the hands for about half an hour a day for 7 to 10 days in a row might help.

Not sure if it will but I guess it's worth a try, anyway.
