Migraine Monday

Woke up at 4:30AM with a Migraine. It was relentless. It lasted most the day , to spite Relpax, coffee, and Excedrin migraine. I get sensitivity to light, sound with nausea and dizziness. It seems to attack me neurologically, recall, memory, balance, slurred speech. It looks like a stroke. What was the trigger? The only thing out of the ordinary that I ate was Hardees. I googled it and it has MSG in everything.
