you can have three of your sinuses infected but the this is consider one infection. assuming you are talking about your paranasal sinuses you have a pairs of frontal sinuses (forehead) maxillary sinuses (below your eyes in the cheek bone) an ethmoid sinuses (on each side of your nose). it really doesn't matter if you had sinus infection in all six paranasal sinuses they are treated as one. i also hear people say they had "double pneumonia" or a double-ear infection. they are referring to an infection (one infection) that may be in both ears or in both lungs.
is it possible to get three sinus infections at the same time? . my friend went to the dr and she told me they said she had 3 sinus infections at the same time. ive had multiple sinus infections before but not all at the same time. is that even possible?
