I've seen that when i was looking for my tense , its the same thing except you put that on your head , i just worry that it may trigger migraines ? have you tried a normal tense for pain block ? amazon i really good one and its on offer for around 70 pound i have two so i can have 4 pads on at one time a the pain is so bad , they are really good and u can't notice then when they are on i just put the remote in a tiny bumbag under my clothes , if you but the head one please let us know how it goes :) good luck
