How Acupuncture works in Migraine head Ache? Acupuncture is meant to keep the energy flow (called “qi”) balanced along the meridians. An acupuncturist will place needles at specific pressure points, usually along a person’s back or neck where they can slow pain transmission. Sometimes, a gentle head massage accompanies the placement of the needles. Treatment takes about an hour, and patients are advised to undergo at least six sessions, usually once a week. The acupuncturist may also suggest dietary changes. For example: Caffeine can exacerbate migraine, and some acupuncturists believe it disrupts the flow of the body.
