I had accupuncture for chronic sinus conditions with awful headaches that I could not shake in 1999 . They put needles all over your body on certain points not just in the affected area. (probably 20 needles each visit) In all my treatments I only felt one needle go in. I would try it again if past all other treatments.
I found a doctor at our local hospital in the pain management clinic and I called my insurance plan and asked if he was in it and he was. My accupuncture only cost $10 a visit. No electric stimulis or other gizmos.
