Tioconazole
"I bought this yesterday afternoon thinking it would be a quick and easy fix to a mild YI. I inserted the treament at around 10 pm feeling a very light burn...... it is now 2 am and my vagina feels like is on FIRE!!!!! of course I freaked out and started reading reviews and it seems to be a normal reaction. The pain is unbearable !!! I can't sleep from the pain and itching!! I have a high pain tolerance but this feels like acid was poured all up in my lady parts!!  and there is a fire breathing dragon inside me! This sucks!"
