Let’s break down the anatomy, the mechanisms, and when you should worry. To understand sinus-related dizziness, you have to look at the eustachian tubes . These are small canals that connect the back of your nose and throat (the nasopharynx) to your middle ear. Their job? To equalize pressure and drain normal fluids from the ear.

| | Inner Ear Vertigo (BPPV/Meniere’s) | | :--- | :--- | | Feels like wooziness, rocking on a boat, or floating | Feels like violent spinning (room rotates) | | Worse when bending over or changing head position quickly | Worse with specific head movements (looking up, rolling in bed) | | Accompanied by nasal congestion, facial pain, thick mucus | Accompanied by tinnitus (ringing) or hearing loss | | Lasts days to weeks (chronic) | Lasts seconds to hours (episodic) |
