Sinus infection, or sinusitis, is an inflammation of the sinuses and nasal passages. A sinus infection can cause a headache or pressure in the eyes, nose, cheek area, or on one side of the head.

Breathing in this moist air can soothe irritated tissues and swollen blood vessels in your nose and sinuses.
