I found the source of my pain...the posterior hardware (pedicle screws and rods). Surgical removal
(09/07) of the hardware released that Lumbar triangle of pain. I still have some hip and knee pain which is a result of L4 and L3 bulging in reaction to the hardware and associated muscle tightness, but hope that over time it resolves itself.
I took a risk, my Neurosurgeon gave me a 50/50 chance that my condition would improve or remain the same.
