Sir! I had unprotected oral sex with a sex worker 15 months ago. The lady sucked my penis for about five minutes. 3 days later we again met and fully open mouth kissed. I swallowed a lot of saliva from her. I don t know her status , but she was a kind of lady that she was ready to have sex with people any time. Three months after the exposure I tested for hiv antibody, it showed negative result. But slight fever after 15 days, night sweats, flakes on the skin surface, neck infection, frequent diarrhoea till now. The whiteness on my tongue is increasing. Sir I have not done expensive modern testing like pcr and western blot test. I did cheapest priced antibody test about 7 times , in the gap of every two months after the first test. But my symptoms continue till now. Is it because antibody formation is taking long time in my case? But all 7 antibody test showed negative and the last time i tested was in 15 months? Please sir ! What can I do now ?
