I had a three level fusion with "boo-koo" instrumentation. I am 9-1/2 months post and just wondering if anyone else is experiencing the same thing? When I roll over in bed (so twisting) it still hurts,.... enough to make me groan... Is this normal? And how long (if normal) does it take for "that" pain to go away? Other than that, I'm doing pretty darn good.
