I need surgery on C5-6 & C6-7 to stabilize them.  I have 4 herniated discs in my neck so will fixing these 2 eventually make other 2 get worse?  I just started looking into cyber knife or some kind of smaller operation but I'm really worried about what I've read about screws breaking n also what I will n won't be able to do for myself afterwards? Anyone had simular surgery recently?
