3) Headache
Headaches associated with sinusitis can range from mild to severe and are usually felt around the nose, forehead, or eyes. They can also be accompanied by facial pressure or tenderness. People may also experience a dull, throbbing, or sharp pain or a feeling of fullness in the head.
Sinus headaches can be exacerbated by weather changes or physical activities such as bending, sneezing, or coughing. It is important to note that headaches from sinusitis are typically worse in the morning hours and may improve over the day.
