Hi Cassandra, I am Dr Jignesh , Trying to solve your query. There are not many conditions out there that cause constant dizziness. However, MIGRAINE 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. Take care Give me 5 star rating DR JIGNESH
