Pinner: Acu staple- You have a small staple inserted on a pressure point in your ear to prevent migraine headaches from coming on. I was on 3 prescription medications for my migraines and would still average about 1 a month. When I got pregnant I had to quit taking each of those meds. I then started having multiple migraines each week. At 3 months pregnant I had acu-staples placed in each ear for 6 months. I didn't have 1 migraine, it was amazing.
