I've seen sounds during migraines...kind of like nonspecific visual distortions. Sound has unfortunately been a major trigger for my migraines since age 7. Never heard any colors though.
I occasionally get an aura but more often than not I'm just smacked with the pain.
But with migraines, one's mileage may vary.
That makes sense to me now.
My mom didn't get the aura either. My triggers aren't sound, but lack of or too much caffine, and stress. Stress is the biggest. I don't get them near as often now. Sometimes they are hormonal as well. Noise and light are horrible for me when I do have a migraine.
I asked a pt. (with dementia) "Are you feeling confused today?" Should've seen the eyebrows rise from family and staff ... yikes !! (background info: he was having blood sugar issues) ... Funniest thing is, he answered "No, Nancy" ... (ha ha , his sister is Nancy and she passed last year).
