Yes, I used a tens unit. It didn't really help much, cause it doesn't go DEEP inside as far as stimulation. The point of it is to deliver electrical stimulation to the nerves and mask the pain -- but it just doesn't go deep enough. It's only topical. There is the Spinal Cord Stimulator that they can implant, and I've had that too. They implant leads in the upper part of your back that delivers the electrical stimulation to the nerves, and the "generator" is placed lower in the body, below the waist. I had it implanted for 6 months, but then developed a problem with the "generator" where because I was thin, it started working itself out of me!
I should never have had it in the first place, they discovered, because I didn't have enough "fat content" in my body.
Ask your doc about the Spinal Cord Stimulator (SCS) and see what he says. Hope you get some pain relief soon! God bless and take care. Hugs, Lee
