I have had the TEN'S used at physical therapy and on the 1st I'm going to buy me and my sis one. You don't have to pay for expensive ones you can get them for 20 to 30 bucks and they work great.

Physical therapy turned into a good opportunity to get a TENS unit. The PT ordered it and my insurance paid for everything except $75. I think if you are looking at something cheap it may not work. Your doctor can also authorize one. Good luck.

Thinking about one myself. I get some relief from muscle ointment and heating pad. And long soaks in hot bath.it helps to loosen muscles some, all temporary but helps. Used tens years ago felt like I was being shocked made muscles spasm.

A tens unit can provide temporary relief for mild to moderate muscle pain. Its not a cure all, but it can help within a pain relief regimen. It uses a mild electrical current to disrupt pain signals.

They way I got my tens unit was by going to physical therapy first and then the PT put in a request along with my pain management Dr. for the unit and it was covered through my insurance. Hope this helps to get you to the right direction.
