I also suffer from chronic back pain, I have sciatica, (bad spelling), which includes my entire right leg being completely numb. I also have disc problems,
have you tried Lyrica? this helps with the nerves, eliminates the tingling, pins & needles feeling completly. If you have tried this med. you def. need to. ask your doctor, they probly have samples, you could try. THIS DOES WORK for the nerve problems/pain, and also helps releive the lower back pain as well. I have serious sympathy for you, as I suffer from this daily, for about 5 years straight.
Lyrica, no generics, cause it's fairly new, but it does work. Ask your doctor if this is right for you.
*I am by no means a doctor or medical specialist
just info from my personal exp. as well as from others I know. I hope the best for you.
By the way, I have 3 friends that had surgery on thier back, and they are still in pain, relying on meds 24/7
