With most things find out the medical cause. Then, do your nat'l remedies if you want to.
What if it is something more serious - an imbalance causing a problem with the kidneys?
You'd want to know.
Do some research of probable causes, of course, I'm sure you have already.
"Prepare yourself for the coming astral journey of death by riding daily in a balloon of divine perception.
Through delusion you are perceiving yourself as a bundle of flesh and bones...Meditate unceasingly,
that you quickly behold yourself as the Infinite Essence" ~~Lahiri Mahasaya, the guru of Yogananda's guru.
