Sinus Headache Causes
Inflammation of the tissues lining the sinuses is the primary cause of sinus headache. The inflamed tissues swell and produce secretions that clog the normal drainage system of the sinuses, causing a build-up of fluid and secretions. The pressure of this fluid build-up causes the pain of sinus headache. Inflammation of the sinuses is known as sinusitis. The inflammation may arise due to an infection, an allergic reaction such as hay fever, or to irritation.
Most commonly, infectious sinusitis (sinus infection) is due to a viral infection, but bacterial and fungal infections of the sinuses can also occur. Since the maxillary sinuses are located in the cheekbone, infections of the upper teeth can spread into these sinuses. In very rare cases, benign or malignant tumors can invade and block drainage in the sinuses and lead to a sinus headache.
