I had sex with an escort and undergone tridot test 8 month's post exposure and the result was negative. But I am having sever pain in my throat may be it's a sore throat and cough. I have also developed bumps on my back and thighs which are there from past 3 month's. Some people say that tridot test is outdated and is not reliable is that true and what abt my symptoms am I hiv free.
