Frequency Specific Microcurrent (FSM) is changing the way physicians and patients think about treatment options for pain and many other medical conditions. Exciting data and 20 years of clinical evidence show how frequencies and resonance can be used instead of medications, nutrients and chemical interactions to change tissues and symptoms. The new book, The Resonance Effect, describes how FSM was discovered and developed, how it's changing medicine and how you can use resonance to change lives, including your own.
