Have severe l5-s1degenerative disease, t4-t5 s1 t8 herniations, spondylosis, severe narrowing of lower spine. Never ever took pain killers and I'm 47. For two months I've been on Vicodin,Percocet,didlauted, oxymorphone,valium, Flexeril,soma, Ativan, and none of those provided any relief. I was given fentanyl 25 on the patch for a month and really worked for a bit, but still had to take oxycodone 15 mg for break through. Pain still there.
