vaginal yeast infection
"I never thought to search for reviews before using a medication, but I will from now on.  I used this medication for the first time last night, and by morning my vulva and clitoris were swollen and extremely tender and painful.  It hurts to walk, even, and burns when I urinate.  It seems as though this is a fairly common reaction, judging by the reviews--makes me wonder why this is on the market?"
