I have not posted in awhile. I had surgery in February 09, one level interbody lumbar fusion at L1-S1 with titanium cage, rods and screws. The original pain is gone and I am able to work out with no pain, but I can't stand for more than 15-20 minutes without extreme pain. I get extremely stiff and I feel like there is a brick in my back. As soon as I go sit down, the pain goes away. Could this be from the hardware or scar tissue? I have not been back to the surgeon since my 3 month post-op. He said only come back if I am having problems. I do plan to make an appointment to go back and see him. has anyone else experienced this?
