My best friend pees a lot. Like, a LOT. She constantly has to go and during a regular school day she'll go about 5+ times. And she doesn't drink lots of fluids! She says its not a UTI because it doesn't hurt when she pees. So what is it? Does she just have a really small bladder (this is what she claims is up) or is there something wrong with her kidneys, prostate, etc?
