Hi My grandfather aged 80 have been diagnosed Survical when he was admitted due to vomiting and dizziness. Later an ENT specialist and a Neuro suggested that it is a case of Vertigo. To whom to trust and from whom treatment should be taken because there is not much improvement from ENT and Neuro medicine from past 10 days. Only a minor improvement is there. My grandfather also has high BP problem and regularly takes medicine for it.
