This build-up is either due to an overproduction or insufficient drainage of endolymph in the constant regulation of fluid in the inner ear. Usually, only one ear is affected. The root cause of the process is unclear and may vary from patient to patient, but can have auto-immune, viral, and/or allergic triggers, among others. [2]
A basilar skull fracture as a cause can give the sign of CSF leakage from the ear, nose or mouth. [4] A lumbar puncture can give the symptom of a post-dural-puncture headache. A cerebrospinal fluid leak can be either cranial or spinal, and these are two different disorders. [5]
Endolymphatic hydrops is a disorder of the inner ear. It consists of an excessive build-up of the endolymph fluid, which fills the hearing and balance structures of the inner ear. Endolymph fluid, which is partly regulated by the endolymph sac, flows through the inner ear and is critical to the function of all sensory cells in the inner ear.
Causes of dizziness related to the ear are often characterized by vertigo (spinning) and nausea. Nystagmus (flickering of the eye, related to the Vestibulo-ocular reflex [VOR]) is often seen in patients with an acute peripheral cause of dizziness.

In certain head positions, these particles shift and create a fluid wave which displaces the cupula of the canal affected, which leads to dizziness, vertigo and nystagmus. A similar condition to BPPV may occur in dogs and other mammals, but the term vertigo cannot be applied because it refers to subjective perception. Terminology is not ...
Medical conditions like anxiety causes heavy-headedness too. [5] A sinus infection can cause facial pressure and pain, as well as nasal congestion and headaches, which are also known as heavy-headedness. [citation needed] New users to specific drugs can cause heavy-headedness. Chronic subjective dizziness (CSD) can be related to heavy-headedness.
A healthy middle ear is filled with air, not fluid. Having fluid in there can be uncomfortable, serve as a breeding ground for infection, and not to mention cause a lot of pressure and pain in the ...
Other causes include Ménière's disease (12%), superior canal dehiscence syndrome, vestibular neuritis, and visual vertigo. [16] [17] Any cause of inflammation such as common cold, influenza, and bacterial infections may cause transient vertigo if it involves the inner ear, as may chemical insults (e.g., aminoglycosides) [18] or physical ...
