Hello Zadie, The migraine stops after around 10
Post# of 7791
The migraine stops after around 10 minutes after I put it on my head, but I leave it in place for 30 minutes to be sure that it stays away. I use a wool hat to keep it in place, and place it top-front of my head. That is the place where I felt the headaches most.
Hope this can help you,
