Hi Jen and thanks for the welcome!
I had my Spinal Cord Stimulator put in May of 2006. (I'm working my way to the pump.. :-))
My stim worked real good until I started to degenerate further down. I'd say about 3 years of fairly good pain control but once the degeneration progressed further south it didnt work. It worked about 20% of the time I had it on. So the doctors put me on more oral pain meds. (Yuck) and I was in a wheelchair for a good while. Standing was unbearable. The lumbar ridiculopathy was nightmarish. Electric current flowing down both legs in the back. I had a bandaid surgery that for lack of medical terminology, carved away some of the vertebrae to allow room for the nerve so it wouldn't be rubbing against bone. It worked. I got out of the chair. I was so blessed, I felt normal for a few years. Then in 2013 my doctor decided to put the pump in. He said it would only require 1/300th of a oral dose of morphine targeted right where my pain was. No more nausea, no more constipation, no more feeling the medication. It was going to be much better for me. I had a difficult time with the implant surgery. It normally takes 2 or so hours, mine took 5. The doctor said he got it all hooked up and it wouldn't pump the saline. (Used before the morphine is added) So, he had to back up and find the kink in the catheter. He did and like I said it worked as expected.
It was nice not to have to carry pain meds with me or not to have to keep track of when is it time for my next dose. I felt more free. More pain free than ever.
I've had it 5 years. My doctor here thought my dose was severely high first time we met. I dont remember my exact dose it's something like 4.075 mg per day. Theres not a doctor alive that wont tell you that after a while you build up a tolerance to morphine. It required a little more, and a little more to get the same relief. I hope the trial works for you. Just ask lots of questions. I'm not sure if you read all of what I wrote but not many doctors, very few to be quite frank will fill another doctors pump. Remember this if you're planning to move or travel for a extended period.
Wishing you the best,
