Sinusitis, commonly referred to as a sinus infection, is the inflammation or swelling of the sinus lining. It can be caused by infections (bacterial, viral, or fungal), allergies, or structural blockages in the nasal passages. Untreated sinusitis can lead to chronic infections, headaches, or breathing difficulties.
