Also known as vestibular neuronitis, vestibular neuritis is inflammation of the vestibular nerve in the inner ear, usually as a result of a bacterial or viral infection, such as the common cold or influenza.
The main symptoms are dizziness, vertigo, nausea, vomiting, and blurred vision.
Viral vestibular neuritis usually clears up by itself within a few weeks, although medication may help to relieve symptoms such as nausea and vomiting.
Bacterial vestibular neuritis usually needs treatment with antibiotics.
