As a migraine sufferer myself, I’d like to offer some advice.
Keep hydrated.
See a chiropractor, get the recommended X-rays.
I was having these for months, and they were debilitating. Everyone, from my wife, to my doctor, to the ER when the pain had me out of my mind said it was high blood pressure.
I knew it wasn’t. My neck was killing me, and the hospital said their X-rays didn’t show anything. After seeing a chiropractor he found exactly what was wrong.
