Brief Answer: Your B12 level is in NORMAL range. Detailed Answer: Hi, thanks for writing to XXXXXXX The normal vitamin B12 level is between 200 and 900 picograms per milliliter. Less than 200pg/ml indicates its deficiency in the body. Your value is within normal range and so it cannot be a cause of your anxiety and balance issues. The most common cause of Vertigo is a peripheral cause (the inner ear), and is termed as BPPV (benign paroxysmal positional vertigo). Medications like Cinnarizine or Betahistine are very useful in controlling the acute attacks of vertigo. Head and neck exercises to prevent the recurrences are of great help in chronic cases, which will be explained by the ENT surgeon. As your MRI of brain has turned out to be normal ( balance issues are also caused by few central nervous system conditions), there is nothing much to worry about your symptomatology, as it is a treatable cause having good prognosis. I personally feel that you have to follow the advice given by the ENT surgeon (You can ignore the neurologists opinion,as the MRI scan of the brain is found to be normal). Hope I have clarified your issue. Happy to help further Regards
