On and off vertigo

[1emankcin]

For the past 3 months I have had on and off vertigo. Sometimes just a little off balance, sometimes bad spinning and sometimes totally fine. I went to an ENT and hearing test showed hearing loss in right ear. This is the ear that bothers me most. Popping, echoing, fullness, etc. Had brain MRI 2 weeks ago. Normal. Doc has no idea what it is.
My ear and balance can be fine and then if I move my head a certain way or when I cough or sneeze, even just very minor to just clear my throat, it can set off the spinning which can last all day sometimes. Meniere's was ruled out. Acoustic Neuroma also ruled out.
Cervicogenic Vertigo? Benzo withdrawal? BPPV?
My two theories....I have cervical dystonia (13 years), so I wonder if it is related (cervicogenic vertigo?). I also take valium for the dystonia and wonder if after all these years I might be in benzodiazepine withdrawal. I experienced it one time before when taken off klonopin abruptly, but severe vertigo was not a symptom. Just dizziness, among many other horrible symptoms..
Why would I be fine one moment and then cough or sneeze and then have severe vertigo? I can't figure it out. Any ideas would be great. Thanks very much.

Yes............that's pretty much BPPV.  I've been battling inner ear problems for a while now.   If I get too little sleep, if the the weather is rainy and cold or if I am overly stressed my problems come back.  It's awful, but I've learned to work around this.

Does BPPV come and go like this? I'm fine one minute and then a clear my throat, cough, sneeze or just move my head a certain way and I am off balance. Yesterday a sneeze knocked me out flat on my back all day because I was so dizzy. Then there are days when I do anything I want and I am fine. Is this characteristic of BPPV?
Thanks!

Sounds like BPPV.  Could also be related to your cervical spine.
