Sinus Infection (Sinusitis)

What is a sinus infection (sinusitis)?

A sinus infection is an inflammation of the tissue that lines the sinuses. It occurs when the sinuses become blocked. They can be filled with fluid, bacteria, viruses, and/or fungus can grow and cause an infection.

Sinusitis has many causes which may include, among other things, a viral infection, common cold or allergies.

What are the symptoms of a sinus infection?

Symptoms of sinus infection include headache, nasal congestion/discharge, postnasal drip, sore throat, fever, fatigue, facial pain/pressure, bad breath, and loss of smell. Any or all of these may be experienced.

How do you treat a sinus infection?

Visit Healthcare Clinic if any of the following apply:

  • Symptoms lasting more than 10 days
  • Temperature higher than 100.4 degrees Fahrenheit
  • Multiple episodes of sinusitis in the past year
  • Symptoms that are not relieved with over the counter medicines

Healthcare Clinic can help determine if you have sinusitis and if treatment is needed, or if a referral to a specialist is required. Antibiotics will only help if the sinus infection is due to a bacterial infection, as most cases of sinusitis are initially caused by a virus. Taking antibiotics when they are not needed can be harmful and can cause the development of antibiotic resistant bacteria.

This treatment is available at Healthcare Clinic locations for patients 18 months and older.

Walk in or schedule an appointment at the Healthcare Clinic nearest you.

If you believe you have a medical emergency,  please call 911.
