Hey there newbie, I'm glad Chris found this and answered your post, he's the one to go to for info on the stim. I just wanted to add some positive reinforcement. I worked for many years in physical therapy and have had a few patients with these stimulators and they have all been pleased with the outcome. I does come down to each individual, where the area is that is causing the problems, and what is causing it so as usual sometimes it works, sometimes it doesn't but it's always worth a try.
