Update:
This story had a happy ending. The other day, I ran into the chiropractor and told her about my concerns. She was actually glad that I did. Before I even explained myself, she said that there are two types of chiropractics (paraphrasing), 1) science-based and 2) philosophy-based. She says that she is science-based and all of her treatments are based on double-blinded, scientific studies.
See. Aren't you glad you asked. As stated, I love my chiro. I only went to him as a last resort and he was the only person that helped with my issue. He doesn't get all philosophical and gives me exercises and stretches that work on the imbalances I have. I see nothing wrong with that.
99% of people who use chiropractors are fat fucks. How about losing some weight and that would take care of your back problems?
My guy does mostly sports chiro stuff. Rarely any fatties there.
