Have taken note of your problems in detail.
You hav two issues one is vertigo another migraine.
Both can co exist which is happening in your case,referred to as Migraine associated vertigo or vertiginous Migraine.
In your case CT and MRI brain done its normal, hence structural brain lesions like tumor and strokes are ruled out hence your vertigo is due to peripheral origin.
You need two types of medication one for vertigo (short duration like 14 days)that is cinnarazine or
meclizine combined along with anti migraine drugs like
flunarizine or
propranolol for long duration like 6 months.
I would advise to once again
consult ENT SPECIALIST AND
NEUROLOGIST to perform
Crysatal realignment manuover (epleys) and then start medication.
If you hav any further queries I will be glad to address that, also mention your medications so far for above problems
Wishing you good health. .
