four years ago I began having symptoms I believed to be an HIV infection. I developed a yeast infection in my throat and mouth, developed a large rash on my shoulder blade, had swollen lymph nodes, had hot flashes and chills intermittently, developed a taste and smell disorder, had headaches. I took the rapid HIV1-2 test but came up negative. With the help of my physician, all went away and I was healthy for four years until this all began again. I developed a dry cough, felt shortness of breath, swollen lymph nodes, hot flashes and chills, headache but no rash this time. But I feel weak and fatigued, especially in the morning when I also feel nauseous. I took the test again but came up negative again. My lymphocyte % is 24.7 the differential is 3.2. What is the possibility of two negative tests four years apart without any sexual intercourse whatsoever. And the last time I had unprotected sex was more than ten years ago. Thank you for your time
