Electronic Muscle Stimulator ,,ems,, i have just purchased one of these devices because I had some acupuncture with the electric device connected to the needles last year, and it really helped with pain re-leaf, but it was only for 6 sessions and then i was told i would have to pay private as the nhs does not fund this type of pain management ??great??, now what i am wondering is will i feel any benefit from a ems machine . looking on uTube I feel it would help with weight control, and pain,????????? what do you people know about these devices ????????
