Migraine headaches-what to look out for

My ex wife used to get the worst migraines.
In fact, I'll admit I thought she was being a hypochondriac.
February a year ago, she told her mother she had a splitting headache. She got up to take something and passed out and collapsed.
Turns out she was dead before she hit the floor.
She had a brain aneurysm and that was what had been causing her headaches all those years.
I would be remiss if I didn't mention that she also had extremely high blood pressure. Like 210/125 regularly.
I'm not telling you this to scare you, but it may be worth looking into.
My ex went years trying to get some relief and doctors just kept throwing pills at her. None of her doctors caught the aneurysm until it burst and killed her.
