Is sinus an infection or an allergic reaction?

Sinus infection: A sinus infection will often cause the patient to feel tremendous pressure behind their nose and under their maxillary teeth. Often the patient will report tooth aches and might wonder if a cavity is present. A 7-10 day course of antibiotics usually clears up these symptoms.

Air Space: Sinuses are air spaces in your head that exist to keep your head from being too heavy. The maxillary sinus when infected or otherwise irritated can cause toothache-like symptoms. Sinuses can also become inflamed from allergies. So, sinusitis can be the result of either infection or allergic reaction.

It can be BOTH: Sinus problems can be caused from either allergies or from infection..And even from a combination of both! get it checked by your medical doctor. 'sinus' are spaces in our face, under the bone... Everyone has sinuses.

Good to consider: Allergies can also trigger nasal and sinus fullness, congestion, pressure-like discomfort. In fact, the two are related; allergies make sinus infections more common and difficult to treat. Sinus infections typically produce thicker, yellow or greenish discharge from the nose or throat, which causes cough; also bad breath. Sometimes it is useful to get a sinus CT to tell the difference.
