Hi there, I am a 46 years old physician, who had neck pain for 20 years. the pain became severe and I had 1 ACDF C5,6,7 in 2004 which did not fuse. I worked with a broken neck, until I had a CT scan that showed the non-fusion. Then I had a revision of ACDF a year later which led to unbearable pain. 3 months later, I had the THIRD SURGERY, all anterior hardware removed, and I was fused from the back.Now the pain is unbearable again,,,,,4 years after the last surgery. Anyone with similare experience who had a successful outcome with further surgery???
