I had l4-5 fusion in Nov.2006 and cervical fusion c3-4-in july 2003 and for the last couple of months I have been have horrible leg pain. Its not sciatica-its different more of a cramping pain. I have tried everything and nothing seems to help. I am on very powerful pain meds Fentanyl and morphine and a muscle relaxer-zanaflex so I don't imagine my doctor will give me anything else. If you find a treatment that helps I would sure like to hear about it. Good Luck and I hope you find relief soon.
