Vagina burning

Alright for the last week everytime my vagina is touched it burns like theres no tomorrow! Peeing, sex, just washing make it burn. I have no other symptoms; no smell, no discharge, pain anywhere else, fatigue, swelling, nothing.

And it's not all the time, just after its touched and it lasts about and hour. I dont want to be a hypochondriac and call my dr for nothing.
