Is this herpes?

Please help it started with a few bumps on each sides of the thighs and it’s super itchy but as the days go by it started getting more and more itchy around the labia lips. The lips are bumpy swollen and red right now. It doesn’t hurt to pee and isn’t painful unless I scratch them and there is no discharge. At first I thought it was bug bites but I had a phone call with the doctor and he says it might be dermatitis and prescribed me fungal cream but I’m worried it’s something else. Is this herpes? I’m scared. Thanks guys.
