TENS stands Transcutaneous Electrical Nerve Stimulation. It is a device that sends off pulses that stop the pain signals from reaching your brain. It helps with the body's production of natural pain relievers. I have one that I wear daily to work due to a damaged nerve down my leg along with helping the pain caused by the fibro.

@Yvettsawyer - it is made by Gem-Stim. TENS is a acronym for transcutaneous electrical nerve stimulation. Small, portable with wires that attach to sticky pads stuck to your skin. Small electrical pulses are transmitted to the body, like little electrical shocks. You can google it for more info. Love mine and use it all the time.

@A MyFibroTeam Member Yes the wires will go that far. I have to one on the backside of my knee and still have plenty or wire.

@ Sunnyside136 - I purchased a Quell...$250 and it didn't work worth a hoot for me. It is hard to get the strap tight enough to stay in place on my leg and it was supposed to help pain allover my body and it didn't. I returned it to Amazon for a full refund. I like my TENS machine - it works great because you put it right on the spot that is spasming. Mine was free through Kaiser Insurance but I think they cost about $125.

Sorry for not answering sooner Sunnyshine136. You'll have to check with your own insurance company hon. Worker's Comp pays for mine as a result of a fall I took at work that led to major back surgery and permenant nerve damage done one of my legs.
