I used to suffer with headaches consisting of a band of pressure across my left eye running over my head and down my left shoulder. The experience would last 48 hours and the residual effect would last 2 to 3 days afterwards. I was taking 4-6 strong painkillers a day. After the first treatment I was staggered at the change; to the extent that I could see better. Although the pain took several treatments to go completely, I felt a tremendous alleviation of pain after that first session. Now I see Caryn to keep my system in balance which keeps me really well.
