I have endolymphatic hydrops in one ear. the meniett releaves the pressure but makes me very dizzy for 48 hours. my symptoms started with using new in-ear headphones. could it be a plf?

Possible: Hydrops and plf both can cause fluctuating ear pressure, and hearing loss so may be hard to distinguish. Another cause could be superior canal dehiscence but the hearing loss in this condition is usually conductive. Consider getting fistula test from audiologist. In plf condition usually begins with blow to ear, major baropressure event, heavy straining such as hard cough or lifting heavy objec.
