Get more opinions, especially from a Dr. who is comfortable with artificial disc replacement procedure in addtition to the other techniques.

Be very careful with your back for the time being and take the time to get those opinions. Don't do the inversion table. Don't lift anything heavy. No Chiropractors at this point. I second the recommendation for Mark highly.

If you don't have a good impression of your Dr. (your pilot) then it is not safe (to fly...).

Your back looks like a multi level ADR which unfortunately most insurance companys don't pay for. Many here have had multilevel ADR procedures in Europe where they cost much less then here in the USA and paid out of pocket for them (me included).
