Lumbar fusion ( L-3 to L-5 ). Neck fusion ( C-3 to C-6 ). Both in 2011. March for neck. November for back. I am in more pain now than before. Had MRI with contrast dye on all ( 3 ) spinal section November 2012. All screws.rods.end plates look fine. So why do still have tingling, buzzing, muscle spasms, in my back, legs, arms and neck?
