Absolutely True! I very recently started to get a big headache (not a migraine but still gnarly) and my acupuncture friend hooked me up. It worked beautifully.
She actually showed me how to do two of the points myself. They are the exact same area where some pressure points are for headaches, in between the thumb and index finger. When you close that area and flex your hand muscles a bit, there is a little crease right there, and right there in the muscles. The point is right where the crease ends.
I have done them myself since then with only minor training from her. Any kind acupuncturist would surely show someone the same points. It works and is free!
