The most common causes of sinus inflammation (sinusitis) are irritants, allergens, and the common cold. Any one of these can attack our sinus membranes, causing them to swell and trap mucus in the sinus cavity. The resulting headache, pressure, and aching are telltale signs of a sinus infection.
Is It a Sinus Infection?
How do you know it’s a sinus infection and not just a runny nose? Sinusitis sufferers generally experience several of the following symptoms at once:
- Pain or tenderness in face
- Aching in upper teeth
- Difficulty breathing through nose
- Green or yellow nasal discharge
- Persistent cough
While most cases of sinusitis will resolve with rest and at-home treatment, you should make an appointment with one of our ear, nose, and throat doctors if you’ve been sick for three or more days, have a fever with your symptoms, or have a history of frequent sinus infections.
