Facial pain from sinusitis occurs when the air-filled spaces (sinuses) in your facial bones become inflamed and swollen, creating pressure that may cause pain across various areas of your face. The sinuses are hollow cavities located behind your forehead, nasal bones, cheeks, and eyes, lined with mucous membranes that normally produce thin mucus to trap particles and keep nasal passages moist. When these membranes become inflamed due to infection, allergies, or structural issues, the sinuses cannot drain properly, leading to mucus buildup and increased pressure that can cause facial pain.
In Singapore’s tropical climate, with high humidity levels and frequent air quality fluctuations, sinusitis can affect people, with many experiencing facial pain as a symptom.
