Dear Concerned, Thanks for writing to us. You have not actually given the duration of complaint in history and the age.Do you have family history? Positive prodromal symptoms(blurry vision /nausea) and an impending attack indicated by an aura?As the vomitting relieves the symptoms. This indicates the confirmed diagnosis of Migraine. The migraine is caused by increased secretion of Neurotransmitters in a particular parts of brain causing increased blood flow to certain parts resulting in cerebral congestion and increase in ICT(Intracranial Tension) for a brief interval to even a day causing severe throbbing headache. Kindly investigate(CT Brain/MRI Brain) yourself with a complete work up for migraine by a Neurologist. In addition consult an ENT Surgeon for Vestibular Vertigo. Rule out associated Vestibular Neuronitis produced by improper inputs to brain by the Statoacoustic Nerves(Right and left ) leading to Imbalancing of your body.The only reliable Medicine is Scopalamine Patch placed on the Mastoids behind the ears.Rarely Hyperbaric Oxygen therapy has also been tried. In my view pls consult an experienced Neuro-Physician and ENT Surgeon at the earliest. Wishing you a speedy recovery., Best Regards., Dr Lt Cdr ASN Bhushan. Ex-Navy.
