Miconazole
"I had been experiencing some mild itching  and decided to diagnose myself with a yeast infection. I attempted to go to my gynecologist but they had a two month waiting list. It was only a minute after applying the treatment and I was in excruciating pain. Burning and itching. Rolling on the bed holding myself while crying. The worst of it was over relatively quickly. I decided to get in the shower and try to get most of it out and 30 minutes later it is tolerable. Still some itching but much better now. I'm not sure if it's painful because it's working or not but I do know I will not be continuing the treatment. Going to call my doctor and see if they recommend anything."
