The short answer is While a stuffy nose is the hallmark symptom, dizziness is a surprisingly common—and frustrating—side effect of a sinus infection. Here is why it happens, what it feels like, and when you need to call a doctor. Why a Sinus Infection Affects Your Balance To understand the dizziness, you have to look at the anatomy of your head. Your sinuses are air-filled cavities located in your forehead (frontal), between your eyes (ethmoid), and behind your cheekbones (maxillary).
You know the feeling: the pressure behind your eyes, the throbbing pain in your cheeks, and a nose that just won’t stop running. But what happens when the room starts to spin? If you’re dealing with a sinus infection (sinusitis) and suddenly feel lightheaded or off-balance, you’re not imagining it.
Here is the key: Your inner ear, which is the body’s gyroscope for balance, sits very close to the Eustachian tubes (which drain fluid from the middle ear).
