I have t.e.n.s. units. I use them on my shoulders, knees, legs, and back.They do help relieve some of the muscle spasms and pain. Good Luck.

I'll look today and send it!

Get a RX from your doctor and it should be covered under your medical insurance DME (durable medical equipment) then go to a medical supply distributor and buy the one that is easiest for you to use and obtain replacement parts.

I have one too.... I use it all over the place anywhere that's stiff or painful! Mostly in the small of my back, but on stiff shoulders, knees etc..... It's a small device from Snowden Healthcare (UK) but they will keep phoning trying to flog you all kinds of other stuff! It was under £200 can't quite remember how much - maybe £165? I'm sure they're all similar and maybe you can get them cheaper on the Internet? I wouldn't be without it! Xxxx

I have one but for pain not for spasms I have a tens plus all the same but it dose help all my best
