Personally I believe that the "placebo effect" contributes to the overall outcome of any procedure/treatment/drug etc.,

My advice has always been to go forward with treatment if: You believe it will work for you. You fully understand the risks vs. benefits. You and your doctor agree that it will help you achieve your goals, whatever they might be. You understand that even if it improves your function now, that over time, it may not be as effective as it was in the beginning.

Remember this is likely a life long battle, one that is ever changing - sometimes it will be one step ahead of you and sometimes you will be one step ahead of it.

If you don't believe in a treatment protocol or recommendation it won't likely work.
