A sinus infection (also called sinusitis) is a common condition where the tissues lining the sinuses become inflamed and swollen, often leading to blocked air spaces and mucus buildup. This condition is usually caused by viral infections like the common cold, but bacteria, fungi, allergies, or environmental factors can also trigger it.Common symptoms of a sinus infection include nasal congestion, thick yellow or green mucus, facial pain or pressure (especially around the forehead, cheeks, and eyes), headache, postnasal drip, and sometimes fever or fatigue.
Treatment for a sinus infection depends on its cause. Mild cases often improve with home remedies like steam inhalation, hydration, and saline nasal sprays, while bacterial infections may require medical treatment such as antibiotics or decongestants. In persistent or severe cases, advanced treatments or procedures may be recommended by an ENT specialist.
