I've had migraines off and on since my 20s (I' now 69). Two years ago my migraines became chronic. After a year and a half, I tried Ondamed therapy. The first practitioner I saw treated me generally, and although the frequency of my headaches decreased, they didn't really go away. The second practitioner I saw concentrated treatment on my head. After three treatments, my chronic migraines went away! I had no migraines for several months. Then, during a major weather event, I had another one. I have returned to treatment to "boost" the effect. Ondamed has been used to treat chronic Lyme disease and is FDA-approved for orthopedic healing.
