I went to one for a year. The appointments went like this. I get on table, he uses his little clicker about 3 times, feels my neck bones, feels my lower back, pushes in a couple spots and then says ok you're all done...now pay me
I went 3 times a week for a year and my back is still fucked up. Cost quite a bit of bank too. They are all quacks man. Pain is mental.
