so I do not have to worry about Herpes? I'm worried because I had back pain. That's what making me worry so much because I'm sure it's related to this case. After all the other symptoms were gone, I didn't experience back pain anymore. Although the doctor said it couldn't be herpes if there were no sores, I was puzzled when she said that my back pain could be from my using a backpack. I do not believe this because I've been using a backpack for all of my life since I was in grade school.
Also, the discharge could be a sign of Chlamydia or Gonorrhea. Definitely get tested for those two.
It sounds like it could be a urinary track infection. You should get tested for everything if you've recently had unprotected sex, just to be on the safe side.
