Hello, I am going to start by saying that at one point I was very sexually active and have since stopped having any type of sexual contact entirely. The last contact I had was 3 months ago and before that it was about 2 months. I became ill around Christmas with various symptoms. I went to my family doc and tested positive for Herpes Simplex 2. Never had an outbreak but have had constant headaches and fatigue. I had alot of abdominal discomfort so I went to a GI Doctor. He diagnosed me with E. Histolytica which is an intestinal parasite that may have been exposed through sexual intercourse. I took 11 days of Flagyl and the issue came back approx a week after the Flagyl therapy. I was then refered to infectious disease specialist. My GI doc talked to the disease doc over the phone and was toldto ask me a few questions. I was asked about my sexual preference and possible exposure to HIV. I tested twice for HIV since my last possible exposure and was negative both times. Once about 3 weeks after possible exposure and another time about 2 months after possible exposure. Now I was tested again today and waiting for the results. Why would the doctor suspect that I have HIV just because of the E histolytica issue not resolving after drug therapy?
