...should get an HIV test? I am very worried. I have had sinus issues since I was a young child. I have always had bad allergies and never really breathed through my nose, always been a mouth breather. I also suffer from horrible sinus headaches, this is what prompted me to go in. After examining the doctor told me that most people lose their adenoids by their teens. So it was abnormal to still have them at 31. He told me not to worry but one of the causes is HIV and he wanted me to go to the lab and get tested so he could rule it out. Not worry, seriously!!?? Has anyone heard of adenoids in adults??
