Hi all , Is there any diagnostic tests to verify Vertigo due to inner ear disease. 1)I went to Ent ,he did some hand movements tests said I dnt have vertigo. Could be cervical spondylitis gave muscle relaxant . Didn't change anything . Infact after stopping vertin felt it was better to take it . 2) I went to neurologist , did MRi brain , cervical spine , it was normal except two spots of demyelination which in contrast MRi did not get  enhanced. Doc said means not active . He said I could have vertigo . Now when I am taking betahistine 48mg in the morning feeling fine till night , but early morning again sir is spinning . It's quite uneasy. My B12 , VIT D is within normal range . What should I do next .
