Hi, I’ve been living a nightmare since last October, 9th, when I had a potential risk exposure situation - vaginal short contact (seconds) with a woman sex worker in Brazil. Three weeks later I started to fell all kinds of symptoms, like: fever, dry skin in all my body, rashes, and, the worst of everything, a lipoatrophy in my hands, arms and face and a great concentration of fat tissue in my stomach, backs and neck. I got more than 10 kilos since that time. However, I made four Elisa Assays of 4th Generation (including p24 detection) during this time (the last result I got yesterday - 104 days, almost 15 weeks after the exposure) and all of them were NEGATIVE. Another strange thing was that I found the woman and asked her to perform the test in December, 18h (70 days after the exposure) and her result was also negative ( I presumed that she was also in a window period). However, due to the strange fat tissue mutations I’ve been suffering and also for recent herpes lips manifestations, I’m really sure that I was infected and the result will be POSITIVE in a few days or months. What do you think ? Would be possible to conclude this in our opinion ? Should I perform a NAT test ? Thank you for the answers and sorry for the English mistakes.
