Sinusitis (sinus infection) is an inflammation of the sinuses and nasal passages that is characterized by a headache or pressure in the eyes, nose, cheek area, or one side of the head. Patients with a sinus infection may also have a cough, a fever, bad breath, and nasal congestion with nasal secretions. Chronic sinus infection symptoms can last for years. Sinus infections are distinguished by their duration and their location.
Acute Sinus Infection
When one or more of the sinuses is infected for a short term, it is referred to as acute sinusitis. In ear, nose and throat medicine, acute refers to an abrupt beginning to an infection that can last three weeks to three months. Acute sinusitis is typically caused by a viral or bacterial infection that may eventually disappear without medical supervision.
Chronic Sinus Infection
When an infection lasts more than three months, it is considered chronic and is often caused by allergies or a physical abnormality such as a deviated septum, or malformed bone. Chronic sinus infection symptoms may be less severe than an acute infection but a chronic infection can last for years.
