I had an ACDF on C5-6 almost four years ago and had a great recovery. Last week, I woke up with intense pain and burning in my neck and shoulder (sometimes shoots pain down arm). This time it is on the left side of my body (last time was on the right side and more in my hand). This new pain feels exactly like the pain I had due to my herniated C5-6. I have to call my surgeon, but wanted to find out what other people had similar issues and how the new pain was resolved. Did you have an additional ACDF on the new herniated disc?
