yeast infection?

for the past 5 months around 4 times I've gotten this vulvar burning, so I assumed yeast infection and used monistat and it's went away but comes back like weeks later. there's no itching, no discharge and no oder. just burning when I wipe myself, what could this be?

I tried just wearing cotton underwear, I've also tried making sure to keep myself dry and cleaned but it still comes back. just burning
