I am Dr Jignesh , Trying to solve your query.
There are not many conditions out there that cause constant dizziness
is the big one that does! Miniere's usually causes spells of dizziness with periods of being symptom-free. Rarely does it cause permanent disequilibrium.
Have you had an ENG test as well? The shimmering vision is also a symptom of migraine.
It's a MISERABLE thing to have, but there is help. The key is getting the proper diagnosis and then getting on the right meds to stop it. Try finding a good neuro-otologist. They are especially good at differentiating between inner ear
and migraine. OTHER cause my be INNER EAR DIEASE.
I hope that helps. Please consult ENT specialist
