What are the symptoms of sinusitis?
Sinusitis is an infection or inflammation of the sinuses. There are two broad categories of sinusitis: acute and chronic sinusitis.
Acute sinusitis usually lasts less than three weeks, and symptoms may include a runny nose, nasal congestion, facial pressure, headaches, and fevers. In the early stages, acute sinusitis symptoms may be very similar to those of a common cold.
In contrast, chronic sinusitis usually lasts for several months. People with chronic sinusitis may have a runny nose, nasal congestion, facial pressure, and headaches. They may also have post-nasal drip (drainage from the nose down the back of the throat), cough, and a reduced sense of smell or taste. Chronic sinusitis may be accompanied by nasal polyps, which are small growths inside the nose and sinuses.
