A sinus infection (sinusitis) commonly causes symptoms such as pain, swelling, and tenderness around the cheeks, eyes, or forehead. Other key symptoms include nasal congestion or a blocked nose, green or yellow nasal discharge, and a reduced sense of smell. Facial pain or pressure often worsens when bending over or lying down. Additional symptoms may include headache, toothache, bad breath, cough, feeling of pressure in the ears, fever, fatigue, and sometimes postnasal drip (mucus dripping down the throat). In children, irritability and mouth breathing may occur. Typically, symptoms last about 7 to 10 days for acute sinusitis but may be longer in chronic cases. Severe symptoms such as high fever, swelling around the eyes, vision changes, or confusion require prompt medical attention. Mild sinus infections often improve with rest, fluids, over-the-counter pain relievers, and nasal saline rinses. In summary, the main sinus infection symptoms are:

• Facial pain, pressure, and tenderness around sinus areas
• Nasal congestion and thick discolored mucus
• Reduced smell and sometimes taste
• Headache, toothache, and cough
• Fever and fatigue in some cases

If symptoms persist beyond 10 days or worsen, see a healthcare provider for evaluation and treatment.
