Hi I had in Dec.2010 my first neck fusion of c-5,6,7 because of a buldge disk of c5,6 which was incroching in To my spinal cord. It had started time fail in April 2011 with some broken screws that the Dr. PA told me but nothing was done after 18 month I took things into my own hands had so nerve conductions done and then saw my hand Dr. they both agreed that there was a underlined problem and was told to see a Nerospinesurgen. So I did he Han me do a CT Mylagram which showed a compleat failed hardwere and needed another surgery. So after living for 18 months with this failur with not even any bone growth the Surgen said it was a mess and he had to take c4 now. So my fusion is cc4c5c6c7 and I have problems with my arms left is worst the the right. The Niro conduction says.( bilateral median nerves neuropathy,sensory, L R, demyelinating. bilateral median neuropathy, motor, L R ( left side axonal and demyelinating ,and right side axonal) Could anyone let me know in a way I can understand. I know how I feel and the constant pain and numbing I m going threw I just want to know why.
