A Korean friend introduced me to the Acutouch. Using hers for my shoulder tension, the shoulder seemed to actually drop immediately as the muscle relaxed. I was amazed. I since have bought my own and use it for indigestion, TMJ and pain from sports. It really works. I particularly like the fact I can treat myself when the need arises and not have to wait to see an acupuncturist. It saves me time and money and shortens recovery time. I highly recommend it.
