i am so disheartened today. I had vestibular testing and evaluation in January which caused my vertigo to spiral into violent visual hallucinations. After hospitalization, 4 months of intense suffering and like 7 drs later, I found what I thought was working for me....Physical Therapy exercises 2 x a day, Upper Cervical Chiropractics, and CBD oil. I hadn’t had a severe attack in a month and a half. Today I had an adjustment and an hour after, I had a severe attack while shopping...thank God I had a cart. Very upset. Wish I could get some definitive answers.
