Generally that's what studies do; you can't really disprove things like naturopathy or chiropractic care, all you can do is show that they do not have any evidence to support them.

I can't speak to your particular medical condition, but I can say I know people who say the exact same thing about acupuncture; they absolutely swear that it helps treat their pain and they are sincere in their belief just as I am sure you are sincere about your belief.

Thankfully science is not about sincerity in one's own beliefs.
