Monistat side effects

Hey ladies! So we all know how annoying yeast infections are! So I currently self diagnosed myself with a yeast infection, I have all the signs except for the chunky discharge. So I picked up some Monistat 7 at the store, and this is the second day of treatment. Anyways, everytime I put the cream in with the applicator, my vagina feels like it's on fire!! Like it's going to burn a hole in my pelvis area. I read the box and it's says "may cause mild increase in burning sensations". But this isn't mild, it's really bad!
