although a bladder infection is the most logical basic diagnosis
if she has discomfort often and they can't find infection
she could have interstitial cystitis. they will automatically see blood cells
how to make sure that there is an actual infection.
so I would recommend seeing a urologist.
* women who are put on antibiotics should always follow up with a probiotic
my doctor recommended repHfresh pro- B
which is specifically for the bladder.
a secondary note, my OB GYN Dr help me solve a lot of issues.
