Pain in kidney while urination. Two days now. No fever at this time.

If it really is your kidney that is hurting, then of course you get to a doctor as soon as possible. There is no home remedy for a bacterial infection that deep inside you. IF that is what it is.

Also realize that the way the nerves are wired in your body will give you false information on the location of visceral pain. So a pain where your kidneys are might actually be intestional or elsewheres.

Two days with this... you should see a doctor.
