Sinusitis

  • Reviewed by Howard E. LeWine, MD, Chief Medical Editor, Harvard Health Publishing; Editorial Advisory Board Member, Harvard Health Publishing

Sinusitis refers to inflammation of one or more of the sinuses, most often caused by infection. Sinusitis can leave you with nasal congestion, facial pain, and headaches. You may also experience loss of smell or taste, fever, cough, or bad breath.

Most cases of sinusitis are acute, meaning they last less than three weeks. Acute sinusitis may clear on its own, but home remedies and over-the-counter medication can help to relieve symptoms.

In some cases, symptoms last longer or may recur multiple times per year. This is called chronic sinusitis. With chronic sinusitis, it’s important to look for the underlying cause when possible because that is what guides treatment.
