I am 29-year-old, married male. I have a baby who feeds on breast milk. I had a sexual encounter before 8 months with a professional with a condom. I am 95 % sure that my protection was intact. Then I started reading about the HIV symptoms and technicalities of testing online. Five days later, I went to a Dermatology and Venereology specialist and described about the incident. He was confident enough that he advised me not to go for any testing. Although my fear of infection remained.
Around two months post-exposure, I felt tenderness here and there like on the back of my head, arms, one lymph node in my underarm was swollen and I developed cold and cough. I started sweating during that time as well. I looked a bit thinner. I got panicked and went to the doctor again. He checked me and was still confident that I am not infected. But for my mental satisfaction, he prescribed me thorough testing which includes HIV1/2, VDRL, HBsAg, HCV along with urine R/E, M/E, C/S analysis.
On 74th day post-exposure I took all those tests and they all came back negative. After lapse of a few days again I felt some skin irritation on the back and burning sensation on my forearms. Although no skin changes can be seen. Again I got panicked thinking that I may be in the window period for HIV. But the doctor remained confident and he advised me not to go for any repeat testing. But my sense of fear, anxiety, panic, guilt, and impurity continues.
On 110th day post-exposure again I repeated the tests but I excluded the urine analysis this time. All the tests came negative again. The HIV tests were fourth-generation combo test both the time. I am on the eighth month post exposure. Still, I feel tenderness hear and there. Recently, I am developing small red blood vessel like dots just underneath my skin on my hand and feet which is staying for 5-7days and going away leaving faint black spots. I again showed it to the same doctor. He is confident and repeatedly asked me to stop worrying. He also gave me anti-anxiety, anti-OCD, anti-depressant drugs.
I am also taking sessions with a psychologist. But still, my mind is not free from the fear of HIV and also fear that my wife and child might get infected by me.
My questions are, do I need to repeat any test to out rule the probability of HIV? Are there any probability of error from lab test given the fact that I took the tests twice? Do I need to worry about the window period as there is conflicting information available on the internet? Do I need to worry about the phenomenon of delayed seroconversion? Do I need to opt for the tests from a different lab? Do I need to worry about HIV 1 or 2 anymore? How to unroot the fear from deep inside my mind? Any other opinion on my history?
