Had a ACDF of the c4-5 in 07, never stopped pain. Now they say problem has been coming from the c3-4 the whole time. And it was found at the same time. And now two years later I have to have a ACDF at levels c3-4 and c5-6. I am 33, how much more will I loose by fusing two more levels? And will I still be the active mom?
