Sinusitis is an infection of the sinuses that can cause a variety of symptoms. It can be caused by a virus, bacteria, or fungus. It can also be caused by allergies or environmental irritants.

When to See a Doctor
Most cases of sinusitis can be treated with over-the-counter medications and home remedies. However, if your symptoms do not improve after a few days, or if they become worse, you should see your doctor. You should also see a doctor if you have a fever, severe pain, or thick yellow or green nasal discharge.
Diagnosis
Your doctor will likely diagnose sinusitis based on your symptoms and a physical exam. They may also order tests, such as a CT scan or nasal endoscopy, to confirm the diagnosis and determine the cause of the infection.
Treatment
Treatment for sinusitis will depend on the cause of the infection. Treatment options may include:
- Antibiotics, if the infection is caused by bacteria
- Antifungal medications, if the infection is caused by a fungus
- Nasal corticosteroids, to reduce inflammation
- Decongestants, to reduce swelling in the nasal passages
- Nasal irrigation, to flush out the nasal passages
- Surgery, if the infection is severe or chronic
In most cases, sinusitis can be treated with medication and home remedies. However, if the infection is severe or chronic, your doctor may recommend surgery to remove the infected tissue and restore normal sinus function.
