Mimi,
Hi, In August it will be 6 years since diagnosed with RSD, which is now full body. However, I have my tens for 5 years and I was told if it worked then give it a name because it will become my best friend. I wear my tens 24/7, and there is no doubt about it, it helps cut down on some of the pain. I do take a lot of meds still, but it does make a difference. I have had to have my tens repaired about three times in the last 5 years and until I get a replacement I count down the minutes because my pain is much higher. The company I deal with is very good about sending one out overnight because they do understand.
I know through experience that with RSD everyone is different and what works for one does not for others ,but I believe it is worth the try. You can rent one on a month to month basis until you see if it helps, before you purchase one. I noticed a difference within a day.
Best of luck! If you would like any other info just send me an email.
