I was with a guy 8 days ago, the next day (thursday) I started feeling itching and burning. Thought it was a yeast infection . By Sunday I couldn't stand it and went to the ER. Treated me for yeast, was still itching and burning Monday and went to urgent care, still said it was yeast. I went to my gyno Wednesday and she said everything looked fine. She said I would have lesions with the itching and burning but I don't have any. I was tested negative for trich and BV. Is this herpes or just my imagination running wild ?
