Endolymph is a fluid that normally fills and drains from the inner
ear and helps a person maintain a sense of balance.
If endolymph builds up in the inner ear, a person may experience a
spinning sensation or dizziness (vertigo), a roaring or buzzing in the ear
(tinnitus), or a feeling of pressure or fullness in the ear. Eventually, this
may lead to hearing loss.
