I too have complex migraines... I've had every test there is... muscle biopsy, eeg,emg,ekg... I mean everything and there is no other problems or reason. I also have developed asthma recently and seem to trigger a complex migraine from the albuterol so I no longer use it and am confined to my house on humid, warm days.
I become paralysed for up to 5 hours with several short episodes for the next few weeks. I also take 4 months to get over the fatigue and mental "slowness" follows.
It is very scary but after 5 years I'm learning to live with it. I've also tried topamax, depracote and am now on lamictal... at least the last lets me think and talk and keeps me kinda relaxed. i've also taken a disability retirement. Good luck, keep in touch... Trisch
