vaginal yeast infection
"This is the side effect: Imagine a raft of fire ants hunting you down and taking up residence inside your vagina. That's the best way to describe the feeling I got less than a minute after using this product. The pain lasted 2 hours, until I washed out most of the cream. Only did one day of the 3-day treatment course, then went to see a doctor who prescribed me an oral anti-fungal medication. 
I've actually used this successfully in the past with minimal side effects. But this time...nope. If you are a person who has sensitive skin (or if you're already feeling irritated from the infection) I would not recommend this. The copay at the doctor's office for a pill was 1000% worth it."
