Has anyone with tingling/burning sensations in their legs have had improvements after ACDF surgery? If not immediately after surgery has it improved over time? I have really no other issues other than this and a little stiffness in my neck. Is paralysis the highest risk if involved in an accident such as a fall, car accident, etc….if no surgery? Does surgery eliminate this risk? What is the % of non-fusion or adjacent segment disease? And what is the % of revision surgery?
