Hi, Thank you for posting your query. I have noted your daughter s symptoms. They are suggestive of an acute migraine attack with visual aura. In this condition, there are visual symptoms such as flashes of light, etc, followed by headache, vomiting and dizziness. She should be shown to a neurologist, so that she can be started on appropriate medications to prevent the recurrence of such episodes in the future. There is no need to worry, as she would get well with treatment. I hope my answer helps. Please get back if you have any follow up queries or if you require any additional information.
