Most people feel "off-balance," "heavy-headed," or like they're walking on a boat. True spinning (room going around) is less common.
| Type | Sensation | Likely Mechanism in Sinusitis | | :--- | :--- | :--- | | | Feeling faint, woozy, about to pass out | Systemic inflammation, fever, dehydration, vasovagal response to pain | | Disequilibrium | Unsteady, off-balance, especially when walking | Eustachian tube dysfunction → altered proprioceptive input; also medication side effects (e.g., decongestants) | | Vertigo | False sense of motion (room spinning or self-spinning) | Rare with isolated sinusitis. Suggests viral labyrinthitis, vestibular neuritis, or BPPV triggered by upper respiratory infection | | Head motion intolerance | Dizziness only when moving head quickly | Often due to middle ear effusion from eustachian tube blockage | sinusitis and dizziness
| Condition | Key distinguishing feature | | :--- | :--- | | | Dizziness episodes lasting minutes to days, often with or without headache, triggered by weather changes or certain foods | | Meniere's disease | Episodic vertigo (20 min to 12 hours), fluctuating hearing loss, tinnitus, aural fullness | | Orthostatic hypotension | Dizziness upon standing, resolves when sitting, not associated with nasal symptoms | | Cardiac arrhythmia | Palpitations, chest discomfort, syncope (fainting) | | Anxiety / hyperventilation | Perceived dizziness with tingling fingers, rapid breathing, situational triggers | | Cervical vertigo | Dizziness with neck movement, history of whiplash or cervical spondylosis | | Post-COVID dysautonomia | Chronic dizziness, fatigue, brain fog, often with normal sinus imaging | Suggests viral labyrinthitis
