Sinusitis (sinus infection): Sign, Symptoms and Diagnosis
Sinusitis (sinus infection): A condition in which the cavities around the nasal passages become inflamed. It is very common more than 10 million cases per year (India).
Acute sinusitis can be triggered by a cold or allergies and may resolve on its own. Chronic sinusitis lasts up to eight weeks and may be caused by an infection or growths. Symptoms include headache, facial pain, runny nose and nasal congestion. Acute sinusitis usually doesn’t require any treatment beyond symptomatic relief with pain medications, nasal decongestants and nasal saline rinses. Chronic sinusitis may require antibiotics.
SymptomsSinusitis symptoms, whether acute or chronic, frequently develop after a cold or during times of severe or ongoing allergic rhinitis symptoms. The most obvious sign of sinusitis is a painful pressure in the cheeks and forehead. Other symptoms include:
- Thick yellow-green nasal discharge
- Postnasal drip, often with a bad taste

Allergy testing performed by an allergist/immunologist can identify what allergic triggers might be behind your chronic or reoccurring sinus infections.
In chronic or severe cases, your doctor may also examine your nasal passages using a technique called rhinoscopy or nasal endoscopy. In this procedure, a thin, flexible instrument is inserted up the nostril to view the sinus passages and look for blockages.
Your doctor may order an MRI or CT scan to look for abnormalities in the sinuses – narrow drainage passages, polyps or a deviated septum.Make an appointment with your doctor right away if you have: a fever, pain or swelling in the face or eye, redness on the cheek or around the eye, severe headaches, confusion or a stiff neck.
