I read in a blog a while ago about someone who suffers from migraines and always meant to post this update in the hope that it may help others.
My son has suffered from migraines since he was 10, he will be 40 this year, it was an aftermath of gladular fever. He tried Bowen Therapy which had been suggested to him by the practice nurse.
Four sessions later over a period of about 6 months and he has not had one migraine, gets the occasional head ache but who doesn't.
So if your life is being made a misery from this terrible pain, check out your local health practices and see if they have a Bowen Therapist, it may help you as its helped my son. The other thing she told him was that he grinds his teeth in his sleep (his wife's been telling him that for years) this is also a cause for bringing on migraines. A tooth guard can also help with this problem and your dentist should be able to assist with that. He hasn't needed to get one as the Bowan has reduced the teeth grinding also.
Hope this update is of some interest to you sufferers.
