try and use a squirt bottle, fill it with warm water and baking soda, and squirt it on the area, it doesnt help tons, but it defiantely helps a bit. Definately go get checked out, i also know of a girl who tryed ora-gel, i dont know how safe that is but it may numb it a bit, so i dont know if you wana try that, but you can also just try and keep the area as dry as possible by just putting baking soda directly on. ( if it is herpes, the sores will heal faster this way it can take anywhere from a few days to a few weeks for them to completely heal.) I hope everything works out for you.Also, if you are too young to go alone, maybe go with your boyfriends mom or someone who is older and you are close to and can trust.
These arent professional answers, just coming from what people have told me and ive experianced.
its safe to get checked out but check and see if you have any soars, blisters,redining and puffyness in the vaginal area in the next few days. but most likely not
