2 day migraine! HELP

So I’m prone to migraines but I only get them once or twice a month and they usually only last for a few hours. At the same time, usually they’re based on me not getting enough food or sleep and I could always take good old excedrin to help. Well since week 3 I’ve known I can only take Tylenol.

It’s not going on 2 days and I’ve tried everything from more sleep, more food, more water, relaxation techniques, & Tylenol.

BTW, I checked my blood pressure with an at home machine. It’s totally normal.

NOTHING is working and I’ve never had one be this intense for this long. HELP!!
