What surgery did you have? Did you have a
mini-laminectomy or full laminectomy with
vertibral fusion or did you get the
artificial disc?
Just because you have followed dr's orders
doesn't mean that you cannot or will not
have either a relapse or even more
difficult to deal with, another disc with
herniation/tears/bulges. Disc faliure is
not uncommon and if you had fusion, you
probably had another disc that was going
bad but had not caused you problems yet
and with the repair/stiffining of you l4/5
space another disc above or below may have
been put in the perfect condition to fail.
If you got relief from the first surgery,
you will probably get great results form a
second if it becomes necessary.
This is just an idea and I am not a doctor
at all. For further help with questions,
