You did not say what kind of spine surgery you have had that left you in more pain that before surgery.
Without knowing what your diagnosis is and what type of spinal surgery you already have had, it is difficult to offer any suggestions.
What you have said though, does indicate only passive treatment and pain meds since your surgery.
Decompression tables can be helpful for some, but have a tract record of making the situation worse in many patients, and the same can be said for the use of chiropractors.
It could very well be that you have very weak muscles, cores, quads etc and without a good solid physical therapy spine program and continued exercises at home after you have completed a round of physical therapy, may be some of the cause of your pain.
A pain pump is usually suggested as a last resort to help a patient deal with pain. That is after all other surgical and conservative options have been exhausted.
It sounds like you have not reached that point, if you think that more surgery would be suggested when you see this new spine surgeon.
If you can provide more detail ie. surgery, diagnosis when you had surgery, what your diagnosis is now. it would be more helpful to getting some advise.
