FSM is a Fancy tenS Machine…. Frequ ency Specific Microcurrent (FSM) is an exciting new way of treating nerve and muscle pain and many other conditions using specific frequencies
Designed for Nerves and muscle pain. A cheaply made machine which uses such low voltages, you would be lucky to get any body penetration.
I wouldnt be using this on chronic diseases, unless its specifically for some kind of pain management, even that would be questionable.
