I don't have the bad pain like most talk of either.
I get the feeling like I need to go but not much does, and just a general continuous discomfort & urges feeling.
If I ignore that, it will travel up the tubes to my kidney and that hurts like a knife in the side!!!

i get the real cranberry juice, some of those AZO tabs or other UTI stuff from the natural health section and flush it out with lots of clear fluids.
and if on other meds check for safety before using any of those.

I've had it turn around in a day or so and then continue to drink extra fluids for a few days after.

Of course if that doesn't work for you and things get worse then a dr is the way to go.
avoid spicy foods, sugary drinks - soda pop,etc

have some yogurt also
