Sinus Infection Symptoms Dizziness Direct

A sinus infection (sinusitis) can definitely cause dizziness, though it is often a secondary symptom. The primary cause is the between your sinus cavities and the inner ear , which houses your body's balance center. Why It Happens

If you feel pressure in your ears, try this simple technique: pinch your nose closed, close your mouth, and gently attempt to blow air out of your nose. You should hear a "pop." This helps equalize the pressure in your ears. Do not blow too hard, or you risk damaging your eardrums.

In some cases, a viral or bacterial infection can spread toward the vestibular system (the part of the inner ear responsible for balance), causing a true spinning sensation known as vertigo.
