The Infratonic is a very interesting piece of equipment. The first time I used the machine, I had been walking for six hours and my feet were screaming for mercy. Using the Infratonic on the bottom of my feet provided great relief and fully energized by legs. I had a lump on my leg for approximately four years: The Infratonic machine dissolved the lump in a couple of days. The machine has also helped a painful hernia, ringing in the ears and extremely sore muscles due to over exertion. I have found the Infratonic to “Tone-up and Tune-up.
