My insurance paid for my tens unit several years ago. It was prescribed by my physical therapist, or he had my pcp precribe it for him. It worked really well for quite a while...BUT....now that I am having muscle spasms and restless legs (and arms) it just really irritates and makes those symtoms so much worse. So I haven't been able to use it for quite some time.

I used to wear it to work, classes, anywhere I was going (as needed). And just turned it on and off throughout the day. It really helped me a lot for my back pain. Anyway it helped me make it through the day.

My mother also has one that she uses on her back frequently and it really helps her.
