As requested I am writing about my experience with the Tens Unit and my sciatic pain.
My husband picked this unit up on his Vegas trip and for a week I alternated heat and ice and wore a back brace with not much improvement. I asked him about trying it out and he gladly helped me.
I have no idea what settings he puts it on , but do know it is trial and error to find a comfort level that I will tolerate for 10-20 minutes. I do know that I like the kneading type rather than a pulsing motion.
After doing it the first time right before bed at a time of day when the pain was at it's worse level, I couldn't believe that it didn't hurt at all. I went to bed, pain free.... Let me just say that I was very skeptical of this machine and was just in such pain I was willing to try anything! The following morning I awoke with a very mild pain that built up as the day went on. Once again I used the Tens Unit for about 15 minutes, but this time I added it in behind my knee which was hurting from an injury exercising. Two days on me knee has done wonders... It is almost totally pain free! Going from a level of about 7 to that is wonderful....
I also have pain in my shoulder that goes along with my sciatica and used it there. Once again immediately after finishing treatment, I was astounded that the pain was gone and I mean completely gone... I did this before bed and went to sleep, awakening pain free, but alas like the sciatica in my lower back it comes back as the day progresses...
The most notable pain free experience has been that radiating pain down my buttocks , which I treated on the first day of usage and it has not returned at all.... Not a normal thing with my sciatica at all... It always radiates...
After day 3 of this I am sold on it's benefits since it worked on several areas. I am going to try to use it tomorrow before the sciatic pain begins and see what happens....
