Tried to get my late XAH, who had awful migraines to follow this idea...got told "no way", and he had them for next 30 plus years.
As soon as you feel a migraine coming on, put feet in water as HOT as you can stand it, and an ice pack on your head. I have used frozen peas for this.
The trick is to get the head cold and feet hot ASAP, before headache gets full blown.
Had this idea from doctor when I had cluster migraines and demented after constant pain for near on a month, it worked for me, and has for lots of others.
Hope it works for you.
God bless
