I tore a muscle in my back, caused by coughing. It caused me excruciating pain. In the belief that it was a broken rib, an x-ray determined that it was not the case. I was on pain medication around the clock and was told that it would take 3-6 months to heal. By using the QGM frequently, for 15 minutes at a time, I found relief within 2 weeks. I also use the QGM for general relaxation.
