Ok, I'm a healthy white female who had regular unprotected sex with the same person (who reassured me over and over he is negative) since last october. The last time was on February 3rd. On february 16th I had fatigue, coughing, runny nose, and was diagnosed with a sinus infection. I was given antibiotics for it and I thought it went away. This past weekend it returned, this time with swollen glands!! The doctor took blood and did a throat culture, in case I had strep or mono. Neither was present. BUT he gave me a different antibiotic for the sinus infection called Biaxin, for acute sinusitis, which has been working wonders after one day on it. But I just read that Biaxin is given to HIV/AIDS patients for Mycobacterium avium complex!!!! Is it possible that he did an HIV test without my knowledge and is now trying to treat me for it???? Im scared and don't want to call and find out because he might think I'm nuts, or say no. But does this happen? Do doctors do HIV testing without your consent? And then give you medicine for it without you knowing?? And is the fact that my sinus infection returned with swollen glands a sign that my immune system is dying and that I have HIV? Please help
