Could I have herpes?

On May 11th I had sex. The next day I had intense pain in clit, vaginal opening, vagina lips and inner lips. It started burning and itching SOOO bad. 5 days later it was still happening so I took a diflucan pill thinking it was a yeast infection. Within 3 days the itching and burning finally stopped. Then about 4 days later, I now have a sore like spot on the inside of my vagina lip. It is flat but it’s like raw skin about the side of a dime. It looks like it has multiple openings and it hurts and burns SO bad. I have also been having a lot of headaches, backaches and pain in my butt cheeks similar to being sore from working out. Could this be herpes? 

It sounds like it to me as that is very similar to what I was feeling particularly the muscle aches in my butt cheeks. Go to a sexual health clinic so they can swab the sore and check. 

Ahh the lower back pain and aches in my butt are awful. I’m trying to figure out how to upload a picture. The spot doesn’t look like the the pictures of herpes I keep seeing but I don’t know what else it could be. I’m definitely going to the doctor tomorrow.
