Hi, Riccardo, just wanted to pop in to say welcome. I too have had lumbar & cervical fusions done. They were both successful in the doctors eyes because I fused but they never took all the pain away. Has your pain management doctor ever tried any injections? I am in the process of diagnostic injections for the facet joints pinching on the nerves. I've had great success so far with these and will have radio frequency abalation completed soon. Didn't know if this may be an option for you.
I do wish you luck with your trials!!
DDD, osteoarthritis, facet syndrome, fusion surgeries C-5/7 & L-4/5 both in 2006, torn meniscus surgeries left knee 2000 & 2002, buldging disc L-2/3
