Vaginal Yeast Infection
"I looked into it and burning from monistat often occurs when you have an infection other than a yeast infection because the pH levels are different and cause a different reaction. Yeast infections don&#039;t change pH in this way. Use an infection screening kit from any pharmacy and make SURE you only have a yeast infection before using monistat... 

I had only a yeast infection and therefore experienced none of this itching or burning, just light cramps."
