Though, Clinical interrelationships between migraine and epilepsy exist ie, migraine may trigger epilepsy (some epileptologist call it migralepsy), or epilepsy may initiate a migraine attack either before , during , or after the fits
But its crucial to mention what type of epilepsy you had , and what kind of surgery? any surgical complication? to really accept the diagnosis of migraine.
Generally there are RED FLAGS in headache and one of them is a NEW TYPE of headache the rests are
1-a regular headache which changed its frequency, or severity ,
2-or if worsoned by bending forward, coughing, or straining,
3-or any headache gets worse on lying down
4-or a headache waking you up from sleep or its worse upon waking up from
sleep in the morning
if any of the above , I advise you to visit any ER next to you.
About the aneurysm you should be screened by an MRA.
Do you have any family history of these:
1-polycystic kidneys,
2-Marfan's syndrome,
3-or Ehlers-Danlos syndrome.
Hope this is helpful
