Hi i had unprotected sex with my boyfriend 5 months agoand he gave me trich. This was my first time ever having sex but it wasn't his. This happened in October 2016. Trich did not go away the first time with 4 500 mg of metrodinazole. So I went back a month later cause I still felt an slight itch so my doc prescribed tinidazole 4 500 mg twice a day. Could it have went away this time? Or could this be a sign of HIV have read so many stories of trich being a high risk for HIV. I also have muscle and joint pain now. Has anyone been through this and came out negative. Please post if you did. Really freaking out having lots of anxiety. Thanks.
