I get the same hairline sores when I flare…. Didn’t realize it was associated… I get migraines too. Maybe it is all associated after all.

Migraines have some really strange symptoms, and different people get different ones. Perhaps the sores are just one of these symptoms? Here is my example. My migraines come with pain, frequently with spots in front of my eyes, tunel vision, dizzyness, I sensitivity, etc., but they don’t come with nausea (99% of the time). My mother gets this dizziness, she sits down, puts her head down, relaxes, breathes, gets through it. Those are her migraines, no pain or dizzyness, etc. My grandmother got dizziness, nausea, lightheaded, etc. but no pain. Its really strange. Three generations in a direct line. And all of our migraines are different.
That said, could you reach out to a migraine or headache specialist? Or maybe a neurologist. Even if they’re from a distance, perhaps they have some insight?

Gentle hugs

Although I don't get migraines, my father does and what caused his was eating oranges. When I read your post my immediate thought was an allergic reaction to something. It can be very strange what some seemingly innocent food (or other thing) can do. My partner has given up bananas now as they seem to trigger facial nerve pain. It might be worth thinking about; perhaps noting what you eat before a migraine starts up?

Visit www.healthcentral.com; scroll and click on "Migraine." Lots of relevant info. Get Betrayal by the Brain by Jay A Goldstein from your library and read the chapter on migraine; also some good info at the beginning of the book. No idea about the sores. Have you consulted a dermatologist who is affiliated with a teaching hospital? This may be a good place to start.

I know words can't help. I will add you to my prayers.
