Miconazole
"I used this product a few days ago. I didn't experience any pain from it until day 3. The first 2 days just involved a lot of itchiness - extremely intense, like fire ants.

The third day was when I experienced pain. It was like a heaviness coupled with an extreme burning. It was very unpleasant, but tolerable. 

I think the severity of pain and itching directly corolates with how bad the infection is, and I think a small amount of pain is to be expected. If it's serve though, do not continue it, just go see your doc. There are alternatives. Also,don't forget that some std's mimic YI's. If it keeps coming back, it might not be a YI."
