I also have a comment. Fluoroquinolone antibiotics are known to cause neuropathy (which the medical community calls "permanent")

We have people coming to the PN forum often following treatments with this family of drugs. Levaquin is one of them.

Here is one article:

Dr. Cohen has had one patient improve by using IV glutathione therapy. But that is anecdotal only at this time.
Your vertigo may be damage to the nerve -- there are tests for vestibular function to determine that.

Vertigo is very disabling and awful...I've had episodes of that too over the years. Sometimes a virus is at fault, and in my case it was thought to be damage from episodes of childhood abuse. Over the years mine has improved.

There is also a condition called benign positional vertigo, which may respond to head positioning exercises:

If you cannot pop your eustachian tube I'd go to an ENT and see if it can be visualized with a mirror( my son had that done), to see if you have adenoid tissue blocking it. When fluid builds up in the middle ear from blockage of drainage, it presses on the eardrum and creates dizziness. In my son's case, he had to have his adenoids removed. Another approach is to put a tube in the eardrum to allow the fluid to exit and reduce the pressure.

So there are some things to think about. Personally I'd go the the ENT first, and see if a solution presents itself. If not, then the dreaded, Levaquin effects would need to be considered.

Good luck to you!
