I am a 29 year old female, as far as I know I have not had any exposure to HIV/AIDS. I have been having painful lymph nodes all over my body off and on for at least 6 months. They are not swollen and the majority of the pain is in the back of my neck and behind my ears. When they become painful, they also become very itchy. I have no health insurance right now and am really scared about HIV. Can anyone please help?
