i just took this last night and i was so scared cz i read comments saying it burned them more and itched them more but when i had it on last night it did not even burn me or itch me it just felt hot in there some how but it did kinda felt little burning just like 1% burn but other then that i feel like it worked because now in the morning it got so messy and i didnt know so i had to change panties and put a pad on but i dont even feel itchy nor burn like the other days. even if i didnt feel itchy or burn when it was inside would it still have worked atleast?
