Your leg symptoms should not be improved from cervical surgery so that symptom could be expected to continue in some form or another.
HNP at C5-6. There is no mention of what side or if ventral (central) with cord compression. I will assume left sided neck HNP due to symptoms “tingling, sensitivity, bruised feeling in left side from shoulders to toe”. The Artificial Disc Replacement (ADR) can be quite effective if the level operated on was causing the symptoms.
You then note “No relief from presurgery symptoms plus additional pinch in left side of neck. Hyper-reflexivity is now bilateral, along with sciatic leg pain in both leg”. Was there cord compression? Was there a signal change in the cord prior to surgery? You had a CT myelogram and an MRI post surgery. What does the radiological report mention?
