"The Power of TENS"

"TENS stands for Transcutaneous Electric Nerve Stimulation. . . . [It] works by disrupting the pain signals originating from the nerves near the pain spot, so the area that would normally be hurting feels sort of tingly. In some patients, the area goes numb after a while. In me, it loosens up my back to the point that, for example, I'm not wincing every time I so much as think about moving and I can actually walk around, bend occasionally, and be more or less functional."
