Welcome to Health care magic.
I went through the history provided by you.
It seems from the history that you are having that you are having migraine headache
and fluctuating blood pressure
is a anti hypertenive drug and you need to continue it as advised by your doctor.
The other symptoms like nausea, dizziness
are because of migraine and these require treatment by consultation with your physician.
Do consult your Physician doctor for examination and treatment.
