Don't overlook kidney stones and/or other potential issues that might be attributed to your condition.

Having said that, your reasoning for getting professional advice does not seem sound.
IMO. it is far better to get a diagnosis than to self-diagnose or medicate at this point.

Having said that Miracle-Mineral-Supplement can be a very powerful infection treatment. However you'd really need to know what's going-on before trying to treat yourself. Kidney pain(or similar) can be caused by a number of things, some of which could be very serious. So do yourself a favor and get checked-out. No one says you need to take Antibiotics if you don't want too afterward.

It's best to be safe in cases such as these.
