Yesterday after the vertigo episcode my head feels very heavy and if I move my head neck I feel very uneasy and feel another one coming..what is the reason and I have taken vertin 28 mg 2 times..I haven t gotten of the couch I feel very scared..  <response>: Hello dear... The reasons for vertigo are:1. Vestibular system pathology it is located in inner ear and maintains equilibrium, when affected it can cause vertigo2. Cerebra poutine angle tumors3. Blood related problems-such as recurrent hypoglycemia Normal MRI is helpful to rule out the presence of any Cerebra poutine angle pathology. So...it will be better to get your blood sugar levels blood pressure checked consult an ENT specialist for proper physical examination. There is no need to worry...you will be fine. Wishing you a good health Thanks take care.
