To answer your questions:
1) It may be possible that the procedure may have irritated a nerve that may be causing your discomfort. From my reading, I would say that this complication is uncommon.
2) A second opinion with another surgeon can determine whether a redo or undoing of the procedure may improve your symptoms.
3) A neurology referral to evaluate whether any nerve disorders can be considered. Electrodiagnostic testing (i.e. an EMG) can be done to further evaluate this. If all the evaluations are not revealing, a referral to a pain specialist to minimize the discomfort can be considered.
Followup with your personal physician is essential.
