Hi Doctor P, I did oral sex to a woman and started having throat discomfort. After a month, I did throat swab and got tested positive for trichomonas vagina on my throat. I took 7 days metronidazole and after three weeks was still having throat discomfort and tested positive again.I took tinidazole 2g three days ago, but still having burning and irritation sensation on my throat..how long does it takes for the symptoms to gradually decrease?Im really stressed about this and I would be grateful for ur advice.Thanks
