Okay I posted yesterday about buying a tens machine, and it came today. I was feeling nervous about using it, but I'm so glad I have! I had a pain in my ankle I couldn't shift, and after using the tens its eased off. I wished I got one sooner! It came with instructions on where to place them, and what program to use for which pain. I would advise anyone with sciatica to get one!!
I keep the leads on all day and just turn the unit of n on throughout the day. One is not supposed to drive with it on so I turn it off when I drive. Think I paid $135 but that was 5-6 yrs ago at a medical supply store
