What causes sinus infection symptoms?
First of all we need to know what the sinuses are. The sinuses are hollow packets of air located on either side of the nose, behind and in-between the eyes, and in the forehead. The sinuses produce mucus that cleans and moistens the membranes of the nose and throat. Each sinus has an opening into the nose that allows for free exchange of mucus and air. Sinus infection symptoms are the result of inflammation and blockage of the openings. The mucus and pressure then build in the sinuses creating a perfect breading ground for bacteria. Sinus infection symptoms generally follow a cold or some other respiratory illness. For someone who suffers from allergies they can also be caused by an allergic reaction. Other causes include: blowing the nose too hard, not completely treating the first sinus infection, or frequent swimming. General sinus infection symptoms: • Headache • Pain • Upper jaw and tooth ache • Tenderness around the nose, forehead and cheeks • Swelling and pressure around the eye
