Abstract Sinusitis (sinus infection) is commonly associated with nasal congestion, facial pain, and purulent discharge. However, a significant subset of patients reports a less recognized but highly distressing symptom: dizziness. This paper explores the physiological mechanisms by which sinus inflammation can lead to disequilibrium and vertigo, outlines the specific symptomatic profile, and provides clinical differentiation from other causes of dizziness. 2. Introduction Dizziness is a broad term encompassing lightheadedness, faintness, unsteadiness, or true spinning sensations (vertigo). While acute labyrinthitis (inner ear infection) is the classic infectious cause of vertigo, chronic and acute sinusitis can also disrupt the body’s balance system. The prevalence of dizziness in sinusitis patients is estimated between 15-25%, yet it is often underdiagnosed or misattributed to other conditions. 3. Pathophysiology: How a Sinus Infection Triggers Dizziness Three primary mechanisms link sinus infections to dizziness:

| Symptom Feature | Typical Presentation in Sinusitis | | :--- | :--- | | | "Floating," "rocking on a boat," or "heavy-headed" (disequilibrium) more often than true spinning (vertigo). | | Timing | Usually constant or waxing/waning with congestion, not paroxysmal (sudden attacks). | | Triggers | Bending forward, rapid head movements, changes in weather/humidity, flying. | | Associated Symptoms | Nasal congestion, post-nasal drip, facial pressure (especially over cheeks/forehead), toothache, hyposmia (reduced smell), aural fullness. | | Exacerbating Factors | Valsalva maneuver (blowing nose forcefully) – can worsen dizziness by forcing air into the middle ear. | 5. Clinical Differentiation from Other Causes It is critical to rule out more serious or alternative etiologies. The table below outlines key distinctions. sinus infection symptoms dizzy
