My Vagina Burns.

The inside of the lips burns and is slightly irritated I know I don’t have a yeast infection(no white discharge), but i don’t know what to do at first it was chaffed and we thought it was just from the pads i was using and just when that clears up It starts getting a little itchy and then it starts stinging, it has been about a week and a half now please let me know if you have any recommendations as far as any creams, or topical treatments that will help.
