VM is likely (also called Migraine Associated Vertigo-MAV), as maatson suggested.
Please consider looking into triggers and underlying causative factors.
-Elimination diet, in addition to the classic food triggers elimination (see details in the site posted by maatson).
- Dr. Coca's Pulse test (takes a week to test anything ingested during that week-free download),
-Thyroid function testing. Low thyroid function is often associated with most of your symptoms,Vertigo, Tinnitus, Dizziness, Dry mouth, Inability to concentrate, Rheumatoid arthritis, Gastrointestinal issues, Premature or delayed menopause...
(not standard serum T3, T4 & TSH thyoid tests, but Free T3, Free T4 & reverse T3 which would more accurately reveal thyroid function).
- Excessive Histamine build-up because of Histamine not breaking down
possibly indicating Histamine Intolerance or low methylation.
If you need more details, let me know, however, please note that my comments and suggestions are not intended to replace medical advice.
I went through this last year, it was horrible. I actually found a doctor that had gone to college and majored in vertigo issues. She worked at an office that did a lot of rehabilitation.
I went in one day for an assessment, then the next time she basically turned my head this way and that. If your ear is hurting or infected, this may help. I had fallen pretty hard and broken my shoulder, and disrupted the fluid in my inner ear. By tilting my head this way and that, she was actually guiding the fluid back to where it needed to be.
I felt better immediately, it was such a simple fix for a horrible ordeal.
I hope you find a cure this easily!
