These cavities are supposed to be air-filled. They produce mucus to keep your nose moist and trap pathogens. However, when a virus, bacteria, or allergen strikes, the lining of these sinuses swells. The tiny openings (ostia) that drain mucus into your nose get blocked. Pressure builds. Bacteria party. You get a sinus infection.
This condition, known as viral labyrinthitis, hits like a freight train. It doesn't just cause mild dizziness when you move your head; it causes sustained, violent spinning, nausea, vomiting, and a profound feeling of unsteadiness that can last for days. This is the most common cause of "sinus vertigo" that doctors see in practice. Benign Paroxysmal Positional Vertigo (BPPV) occurs when tiny calcium carbonate crystals (otoconia) break loose from their membrane and float into the wrong semicircular canal. vertigo from sinus infection
Today, we are going deep into the gooey, congested truth. We’ll look at why your sinuses can hijack your balance, how to tell if it’s just a sinus issue or something worse (like BPPV or a neurological problem), and—most importantly—how to stop the room from spinning. To understand why a sinus infection makes you dizzy, you have to visualize the architecture of your skull. You have four pairs of sinus cavities: frontal (forehead), maxillary (cheeks), ethmoid (between the eyes), and sphenoid (deep behind the nose). These cavities are supposed to be air-filled
