my wife was suffering with migraines for several years, but as of late she went thru a spell where she would [for lack of a better word ] blank out and her eyes would glaze over and she would be gone for several minutes completly nonresponsive. we spent night in hospital under dr care, mri's are clear , eeg's clear. xrays of upper back and chest are clear, but the episodes are still continuing. there is also some upper back aches between the shoulder blades. when they hit but before she blanks out she says she feels like she is going to pass out or is going to be sick. the dr's call them complicated migrains. anyone with anything will be greatly appreciated
