An infection of the sinuses, medically known as sinusitis, entails the inflammation of their inner lining, which is usually caused by a virus. The sinuses are air-filled sacs, which due to a nasal infection or other stimuli, may get filled with fluid; this creates a blockage and allows for the growth of microbes in the sinuses, which produces a range of symptoms. Even though it's a common condition that isn't very serious, sinusitis leads to nasal obstruction which can be very bothersome, especially if it lasts a long time. It's common to mistake a sinus infection for a common cold or the flu. But these distinctive signs will help you determine whether or not it's sinusitis.
Perhaps, the most typical symptom of s sinus infection is pain above or below the eyes or nose. A person has various sinuses behind the eyes, forehead, and nose, which have their specific purpose. The primary purpose is to keep the air warm and moist. Another is to ensure that the head doesn't remain heavy. However, if the holes connecting sinuses as well as nasal passage become plugged, mucus accumulates. This leaves your face feeling heavier than normal. The increased pressure on the facial nerves can be extremely unpleasant and painful. So if you have a sinus infection, you will feel a dull ache in the forehead, upper jaws, between the eyes, or your nose.
