It didn't help at all for me. I knew I was being delusional even going to the chiropractor as the neuropathy continued to spread, but thought -maybe since so many people believe in it, it must have some purpose. I've gone for about 10 sessions including previous times that my si joints had problems. I have never had relief. I can say from my experience it was a waste of money and I know longer believe in cracking and adjustments. I didn't really believe in it in the first place, but wanted to be fair before I could make up my mind.
I think the attention and physical contact that you receive from a health practitioner is what is healing, not being cracked around.
In my opinion, that is why some people get relief. *this is only my little humble opinion* I am opinionated
