I had C7 fusion on 2001, screw blew in 2007, ended up having C4, C5, C6, C7 discectomy w/prosthetic discs, cage, plates and screws at that time. I am currently in Iraq, am having strange sensation, similar to the screw issue of 2007. I don't have many options here, obviously. I am scared and nervous, I cannot go thru that surgery again. Anyone else have hardware failure? If so, what symptoms did you experience?
