Hi, thanks for writing to HCM.
There is no relationship or bearing between the neck surgery
and the development of back pain
later on. Propably in your case it could be a part of degenerative process affecting cervical as well as lumbar spine
. No surgery is needed for mild disc bulges as they can be managed conservatively.
Dont even think of confining yourself to wheelchair. Act promptly. Consult an orthopedic /spine surgeon
and follow his advice accordingly.
Hope this helps
