To understand how sinus issues cause dizziness, you have to look at the anatomy of your head. Your sinuses are air-filled cavities located behind your forehead, cheeks, and eyes. They are connected to your nasal passages and drain mucus.
Sometimes, patients believe they have a sinus infection when they actually have a different condition causing both the sinus pressure and the dizziness.

The short answer is While not the most common symptom, sinus issues can lead to feelings of lightheadedness and dizziness. This is usually due to a combination of pressure changes, fluid buildup in the ears, and the body's response to infection.
Your sinuses and middle ear are connected by the Eustachian tubes. When sinuses are inflamed, these tubes can swell or become blocked, preventing them from equalizing pressure in the ear. This pressure imbalance often manifests as a "floating" sensation, lightheadedness, or feeling "off-balance".
