Tioconazole
"So after reading all the comments, I now know its not just me:( 
Went and got the monistat 1, put it in about 1 today. Felt fine till about 30 minutes ago. Oh my!!!! My inside are on itchy fire. This is horrible. I'm hoping at least it works for all this pain. I can say I will never use this AGAIN!!! What helps with some kind of relief ladies??? Help please"
