HI weaver01 your pretty new from your surgery yet, and it will take quite some time for your ACDF to fuse and completely heal so you might have just strained or. Stressed the nerves from your fused area a little thus causing your symptoms??? In any event I would definitely talk with your doctor and or surgeon about it! I guess it's possible an other disc (either above or below ) your fusion could have went bad, but probably highly unlikely, as usually when something like that happens, its many many years after that fusion!!
In the mean time just be extreme careful and cautious until you can get it thoroughly checked out! Please keep us informed of your progress, when your here on this forum your part of our chronic pain forum family and we do care about each other!
I wish you all the Best!
