Just bought a TENS machine (TENS plus by TBWL) and now I'm worried I've bought the wrong one. Does it have to be a specific 'labour' one or would any Tens machine do?
It came from ebay and included instructions, but I think I'm being a little thick as I can't understand the instructions . It has a low and high frequency setting, but what am I supposed to do with it? How do I use it?
Please explain it all to me in words of one syllable.
