Has someone had vulvar burning? What worked for you?

I have a burning down there in the entrance of my vagina (vulva) after I urinate and wipe it starts burning more, I bought a 3 day treatment for yeast infeccion but I still have the burning, it doesn't itch I don't have any odor or discharge, it's just the burn I told my husband to take a look, he says everything its normal and the skin is not even red or irritated, I have to say I traveled for 5 hours in an airplane with very tight jeans even when a stood up my vagina was numb and I also had to use the public restroom a couple of times, after all of this I started to feel uncomfortable down there, it's been a week and I still have this burning that it's killing me.
