I had ACDF surgery at 4 levels about 3 months ago. It has been a difficult recovery but the bone is growing and fusing quite rapidly. I am in physical therapy twice a week for the last 10 weeks. Problems have been stiff and painful neck muscles and nerves as the entire structure is realigning and adjusting to the PEEK cages. Recently, I have noticed tingling around the top of my spine about 2 inches below the base of my skull. Heating pads have helped. Has anyone else had this issue and what has worked to calm those nerves? Also, how long does it take to feel normal again? I definitely am improved post surgery but it has been a rough few months. Thanks for any advice or ideas.
