Have tried all oral meds, TENS, Spinal Cord Stimulators plus failed back surgery (L5-S1). Only thing that has helped at all was oral oxycodone. Had a pain pump implanted 3+ weeks ago, now receiving .72mg/day of morphine with no relief, maybe actually worsening. Am curious about other intrathecal drugs such as dilauded and, particularly, bupivacaine for treating the neuropathy. Thanks.
