I recently had one night of swollen lymph nodes, fever, night chills, and a short streak of a rash on my upper arm. I m worried that it could be the initial setting of HIV but I am hoping it could be something else. I plan to get an HIV test in two months to check if it s HIV. What else could it be? Our house has had a recent flea infestation. We did flea-bombs with heavy chemicals. I m wondering if it s possible a flea could have given me an infestation or if the flea bomb caused an allergic reaction. Also, I slept one night outside and I m wondering if some other bug could have transmitted some infection.
