I was just diagnosed with a severe sinus infection with fluid in the ears and cobblestoning in the throat. What does this mean. I also have a fever.

Viral vs. bacterial. If a specialist has made this diagnosis, it could be a viral infection (flu) or upper respiratory allergy. Severe sinus infection could also mean a bacterial infection. What it means is that you either have the flu, which is almost epidemic now or you have an acute allergic disease. Sinus x-rays document the diagnosis of sinusitis. Middle ear fluid can be treated with steroids or surgery.
