I am a heterosexual male, 25 year old non drug-user. In July of 2006, while intoxicated, I had unprotected vaginal intercourse, and preformed oral sex, on a woman of unknown status. This occurred only one time. At some time during the five to ten weeks (sorry I don’t remember exactly, but I know it was in the fall or late summer), a lymph-node on the right side of my neck became visibly swollen; I had a biopsy some time later when it did not reduce in size, and the doctors tested it (although I am not sure what for) and concluded that, while they did not know what caused the swelling, it was not a life-threatening concern. I have no idea if they tested it for HIV along with whatever battery of tests. He mentioned some other lymph nodes were slightly swollen. He thought it might possibly be cat-scratch fever. Since, I’ve bronchitis 3 times. Recently, I had ulcers in my esophagus, which the doctors biopsied following an endoscopy and determined were non-bacterial (they were negative, they said, for bacteria or infection) and diagnosed me with esophagitis, caused by not swallowing vitamins with water, too heavy drinking, poor diet, and acid-reflux. I was placed on 60 mg of Protonix. HIV/AIDS was never a concern of mine because I am not sexually active; besides that drunken instance in 06, I have only had one partner, and only for a few months. If helpful, I am taking 100 mg of sertraline, in the form of Zoloft, daily as prescribed by my doctor. I have, all my life, had bad allergies, and in 03 I had pneumonia. While googling repeated bronchitis, I came across a site that mentioned HIV can cause regular recurrences. and that lymph nodes swelling up could have been my body responding to its recent infection by the HIV virus. What is my likelihood of contradicting HIV in the incident I mentioned? What is the likelihood, given that incident and my medical history, that I have HIV?
