My wife and I have received benefit from the use of the Infratonic machine. One treatment relieved low back pain for my wife. She is a teacher and has found that using the Infratonic machine on her feet after work soothes her tired feet, and helps her to sleep well. I have an old knee injury, which was recently re-injured. I used the Infratonic on my knee one night and the pain was gone the next day. I have also used the Infratonic machine on my chest to strengthen my immune system. I have found the added benefit of a good night’s sleep. I am currently using the machine on the dan dien point to strengthen my internal organs, and plan to use it to promote calm in my 10-month-old child as she goes through the teething process.
