Isaac -- that is really informational - the new medical theory of where migraines come from. I've never had suicide migraines (continuous), but for years had really bad ones where I thought my head would explode and wanted to die, also nausea, and painless ones like Nickolas describes. One time, I had a painless migraine and my whole face/throat/chest had no sensation --- I could touch my face and not feel it. Went to the hospital as it freaked me out.
End of the tale,,, after 15 years of therapy for my PTSD (I'm cured!), I no longer have them ... never, for about 10 years. I still have insomnia and night terrors, but the migraines were related to my emotional health. (oops, remembered that I did have one, about six months after I tore my foot - it was an 'ocular' migraine, and I had what looked like water running through my vision) I realize that others get migraine from foods, atmospheric pressure and other causes, so not suggesting that is the cause of anyone elses's migraines.
My body tends to manifest emotional pain physically (fibromyalgia),,, and I am not only free of the migraines, but of the severe bronchitis that would land me in hospital 4-5 times a year. It was all about wholistic healing.
One suggestion for anyone --- as soon as you see the aura,,, take your meds! As expressed earlier, the sooner the quicker. My GP used to say, "when you feel one coming on, hammer the $h*t out of it!"
There is hope for healing, and I'm glad it's much better for you now.
