In a recent study, 24 female patients with fibromyalgia (FMS) were assessed for neurotologic symptoms. The assessments were based on history, physical examination, audiometry, bithermal caloric testing, and auditory brainstem response testing. Almost 50% of the patients had some sort of otologic symptoms. Dizziness was the most common complaint of the patients, and was following by tinnitus, hearing loss, and vertigo.
