EMG is difficult to interpret in the recent postop setting, so the results should be interpreted with caution, its possible there still are spurs compressing a nerve root, but, Probably most of the pain is from muscle
pain and spasm
. If an MRI was not done postop, it should be done to check for
any retained disc fragments, or spine instability.
Perhaps you should get a 2nd opinion from another unconnected group - (not as the above).
