Hi, I had C5/C6 and C6/C7 acdf surgery done in March 2016. I had severe right arm/hand/shoulder pain prior to surgery. I tried epidural steroid injection x2 with not even 1% improvement before opting for surgery. Pain had occurred spontaneously in November of 2015. MRI showed herniated discs at those 2 levels with nerve compression. Right after surgery I had immediate relief with no pain except for minor surgical pain. Wore hard collar 2 weeks. Over past 2 months pain has increased and is now severe requiring pain meds. At last visit doctor said it looks like the allograft has migrated and is compressing the nerves again. He barely discussed the problem and tried to get me out quickly - sending me for 1 month of physical therapy and if no improvement will schedule an MRI. Has anyone had the graft migrate? Did they require further surgery? I have now had 2 weeks therapy with no change. Thanks.
