Sinus problems, often referred to as sinusitis, occur when the cavities around the nasal passages become inflamed or swollen. This inflammation can be caused by infections, allergies, or irritants, leading to symptoms such as nasal congestion, facial pain, and headaches. The sinuses are air-filled spaces in the skull that help with breathing and filtering air. When sinus problems persist, they can affect daily life and may require medical attention. Treatment options include over-the-counter medications, nasal sprays, and sometimes antibiotics if a bacterial infection is present. Maintaining good nasal hygiene and avoiding allergens can help prevent sinus issues.
