vaginal yeast infection
"It burns me after I use it, which is why I learned to use it at night while I sleep, but man it feels a whole lot better after! Make sure you guys actually know it's a yeast infection because those of you who are just using it after experiencing similar symptoms might have BV instead! 
I get yeast infections after using nair hair removal (I never learn my lesson) and I always go to my gyno. 0/10 for burning pain but 10/10 because I feel better after a day."
