The first 3 times I used the mat, I could feel more energy going into my entire neck area where I have had stiffness and possible thyroid issues. My blood test later showed the T3 and T4 count to be normal after years of low thyroid function. The second time, I could feel it in my sore left shoulder. It seemed that the energy was going to the area where my muscles have been in knots for a long time.
