My lower spine never finished growing to the proper size. So when they did the foramanectomies laminectomies and discectomies they tried to give my nerves abd blood vessels some extra room. I think those helps to slow the progress of fusing down in the area some. I have the surgery reports from bith surgeries and am sure glad I was asleep. But it still feels like a big bulge sticking out with more on the right side than the left.
