I have a kidney infection in my right kidney. The pain is pretty severe; it feels sort of like I sprained my back. I am a soda addict so I typically drink a lot of soda and little water. I know this is the cause, but now I am drinking water and I was wondering if there is a natural remedy to speed up the healing process, as the pain is pretty severe. I don’t have insurance so going to the doctor is out of the question unless it is life or death. Please help.
