Okay, well, has anyone had this happen? I had the L5-S1 fusion in June of 08. I just had a ct-scan. It seems the right side fused but the left side hasnt. There's also movement in the screws. Im still in large amounts of pain and have been put on morphine twice a day and percocet for the breakthrough pain and I have ALOT of it. I also take muscle relaxers. Part of my problem with the meds is that Im having problems with my vitals going wayyyyy down on them. Anyone have any advice? Im so sick of pain and the doctors....noone understands cept you guys.
