Yeast infection?

So at first it started out as my vagina being very irritated and I assumed it was from something scented that I used on accident. All that happened was the outside of my vagina got really irritated and all it did was burn. I had to use ice down there to cool it down. I don't have discharge at all, no foul odor or anything like that. And if it's really irritated, it does burn to pee. Idk what to do. I used monistat the 7 day but it only seems to irritate me when I'm hot. I have prayed that this isn't something else which wouldn't be possible but it's really starting to annoy me that it won't go away. Any ideas on how to soothe it?
