Hello, I am 29 years old and had spinal fusion L4-S1 nine months ago due to DDD and Spondelo. I am currently living in Ecuador and having more pain than before the surgery. My Doctors here and in the states say that the fusion was a success and all my MRIs and X-rays look fine. They have come to the conclusion that my hardware might be causing the problems. They suggested a hardware block where they inject an anesthetic around the hardware and if there is significant pain relief than the hardware is the problem and needs to be removed. Has anyone had this procedure and what is the success of hardware removal. Does it feel different? Will I get more flexibility even though the bones are still fused? I feel pain above my fusion when I bend over, will this go away after the hardware removal?
