I had a protected sexual encounter about 3 weeks ago, which included oral. I felt slight nausea and noticed white bumps on the back of my throat and my tonsils. My lymph nodes in my neck and groin were noticeably swollen as well. I went to a doctor with these symptoms and I was tested for strep, and it came back positive. I am now on Penicillin V (500 mg) but I am still worried as the symptoms for strep bacterial infection are very similar to those of the early stages of HIV. The skin around my neck became very sensitive once I began the Penicillin V, but hypersensitivity is a common side effect. What is my risk of HIV and what type of test can I get that would be accurate this early on?
