ok well a tens machine is like a little battery pack that u hang onto your belt of lay on the pillow it has small electrode adhesive pads that stick to the area where the neck join to the back of the head on those ridges it send small elecrice impulses every couple of seconds and u can adjust the amount of shock

a migrain is caused by the small blood vessels in the black of the head being restricted or restricting themselves the small electric shocks this machine provide make the walls of the vessels spasm and open up.

like if u electricute sumthing the muscle contracts then lets go to the full extent.

so the blood vessels open back up to the widest amount letting more blood through .

im pretty sure this is the one my mother has it does not picture the adhesive pads but the main unit.== http://www.bodyclock.co.uk/acatalog/...nsmachine.html

hope this help as i know how much a person can suffer from this.

migrains themselves dont kill but you are right normall they depress people so much they get depressed and dont eat and shit. too right and all imagine having the worst headache in your life for a week then a week later and a week later and sometimes 24/7 everyday for a month.
