Thank you for posting your query at DoctorSpring.com
I have noted your symptoms and would like to reassure you that these do not suggest any serious brain disease.
The most likely cause of your symptoms could be migraine or vascular headache. Sometimes, symptoms may last for 72 hours or longer.
As of now, you can take symptomatic treatment, such as rizatriptan or sumatriptan tablets for headache; and betahistine tablets for dizziness.
BP and cholesterol levels may be checked up to make sure they are normal, in view of family history.
I hope it helps.
