Pain In Inside Of Left Cheek I Have Been Feeling Pain For A Week And A Half Inside My Vagina..but Mostly On My Left Side.?

I have been feeling pain for a week and a half inside my vagina..but mostly on my left side.? - pain in inside of left cheek

The pain is not painful ... rather uncomfortable. My left buttock and leg pain sometimes, especially if you are under pressure to him. My vagina is swollen ... sometimes a little itchy, but not both.
I went to my clinic at the University of Health and described the symptoms to the doctor. She looked at me and said he was flushed and could be herpes ... Although I saw the most frequent symptoms (sores, cuts, etc..) I asked if it could be something else, like an infection and passed everything. No need to test or tests for bacterial infection or not ruled out running?
She put me through the pain to take a sample of the culture, but decided not to use it. Start prescribed Valtrex and told me to treatment orf my appointment. She told me back in 4 weeks for a blood test to see if I herpes. I am taking medication, or should I seek a second opinion?
