I am always getting some swishing noise in my ear. Why?

Hello,

Welcome to icliniq.com.

Since the movement worsens the symptoms, it must be an inner ear problem. There could be an additionally middle ear block or eustachian tube block as the pressure change worsens it. However, since you have not mentioned the duration, I am mentioning all possible differentials.

Recurrent vertigo lasting under one minute is usually benign paroxysmal positional vertigo. A single episode of vertigo lasting several minutes to hours may be due to migraine or transient ischemia of the labyrinth or brainstem. The recurrent episodes of vertigo associated with Meniere's disease or recurrent vestibulopathy also typically last hours but can be briefer.

Further evaluation needs local examination by an ENT surgeon. I suggest you use Betahistine 8 mg three times a day for symptom relief. Consult your specialist doctor, discuss with him or her, and take medicine with consent. It may cause gastritis.
