Hi, I Went To The Doctor And I Had A

Hi, I went to the doctor and I had a STD which I received from my boyfriend. So when he went they told him that he didn't have anything. My question is he was recently shot and the bullet fragment was still in his arm and so they was giving him antibiotics so he didn't get an infection. Could the antibiotics they was giving him get rid of the std. The std was called trichomonas
