I have been diagnosed with epidural fibrosis (a looong time ago). I have had a pain pump implanted for the past 5 years. This is loosing its effectiveness. My question is - is there anything new out there to help with pain control? I've done all the shots, TENS units, narcotics, and currently the pain pump. I am 41 yrs old and have been battling back pain since 1992 when I was in a car crash.
