Sinuses are air-filled spaces in your forehead, cheekbones, and behind the bridge of your nose.
When the sinuses become inflamed – usually due to an allergic or inflammatory response – these spaces will enlarge, creating more concentrated fluid, and the passages that drain them can become clogged.
Accumulation of focal points in the sinuses can cause pain that feels like a headache.
Signs of a Headache Due to Sinus
You will feel a deep and constant pain in your cheekbones, forehead, or the root of your nose.
The pain usually persists when you move your head suddenly or strain. At the same time, you may have other sinus symptoms, such as:
Have a cold
Full feeling in your ears
Fever
Swelling on your face
