You know, I never put that together - but I too get migraines (and have since i was 7), especially when there are triggers; a mean customer, a BANG in the shop when someone dropped something, a man's colonge that he evidently took a bath in... the smell of an old woman that reminded me of my gran. Actually, that reminds me - I forgot that a woman came in who i *thought* was my gran (who i am not speaking to, or her son); had the hair, the coat, the slacks, even the shoes. Panic attack right on spot and i fled the room into the back where i could hopefully calm down. Naturally, calm is not what happened, but crying - until I called my mom who had just gotten off the phone with my gran, so that news made me see my reaction was not based on anything really happening right then. My gran's french and sadly there were already 2 french older ladies in the store before i saw the apparation-gran, and then french music in the store after that - migraine central.
Thanks for posting - you added another puzzle piece for me.
