I had sex 2 years ago and the symptoms appeared 2 or 3 days after that. The doctor gave me a dose of ampiciline, metrodinazol suppositories and tablets for 7 days. And I didnt drink any alcohol nor did I have sex. But the symptoms came back after a couple days. And now I recently finished the second treatment. It was for 10 days and he gave me suppositories and a cream for the itchyness. I dont understand why it keeps coming back if I hadnt had sex since It.
