What is a possible diagnosis for a patient experiencing dizziness lasting for several days?

Vestibular neuritis is characterized by prolonged episodes of dizziness or vertigo that can last for several days. It results from inflammation of the vestibular nerve, often triggered by a viral infection. Patients typically experience sudden onset vertigo, which can persist for days or even weeks. This condition might be accompanied by imbalance, but it usually does not include hearing loss, differentiating it from other vestibular disorders.

In contrast, Benign Paroxysmal Positional Vertigo (BPPV) tends to cause short episodes of vertigo triggered by changes in head position, rather than prolonged dizziness. Meniere's disease is associated with episodes of vertigo along with ringing in the ears and hearing loss, which may not align with the description of continuous dizziness lasting several days. Unilateral vestibular loss (UVL) could lead to balance issues but does not typically present with constant dizziness without other underlying conditions or precipitating episodes. Thus, vestibular neuritis is the appropriate diagnosis given the symptom pattern described.
