I had a thoracic fusion t 8, 9 and 7, 8. It did not help and I have been in excruciating pain for over 20 years. Decided after various other treatments to get the spinal stimulator and it has been the best decision I have ever made. I am mostly pain free my nerves have been angry for 20 years but the stimulator blocks their angry messages to my brain. I was bedridden before the stimulator but now I am able to live again with little to no pain. Hope this helps.
