Lynn,   I think you're probably right that the correct information wasn't passed on to the anesthesiologist. It's also possible that he or she was in surgery and unavailable. IMO, another part of it was that the people taking care of you have no idea how severe a Migraine and its consequences can be.   I had a similar experience with a Migraine, but AFTER surgery. My primary care doc's office was across the street from the hospital. My husband got fed up and went and got my primary doc. When I had to have surgery again, I told the surgeon up front that I would not go into surgery until I saw my chart and saw that appropriate orders had been written in case of a Migraine.   If you ever have surgery again, I'd suggest talking with your surgeon before the day of surgery to be sure he puts orders on your chart in case of a Migraine.   I'm so sorry this happened to you.   Teri
