I would like to inform you that there are many causes of dizziness and needs a complete medical examination and investigations. I would suggest that you should get yourself clinically examined and get following investigations :-1. CTMRI of head and neck.2. ElectrocardiogramECG of heart.3. Hemoglobin level.4. ENT check up. You can take anti vertigo medicine like Betahistine 16 mg 2-3 times a day after discussing with your doctor. I hope this is helpful to you. Thanks.
