I can tell you that my neck is messed up–I went to the chiropractor for the first time last week and have gone to three more visits since then. I feel great once I leave, but the pain comes back in a few hours…I’m thinking it’s a sham. One of my friends said that she went three times a week for three months to get her back pain fixed. That seems a little excessive. I’ve decided it’s a better investment to spend the money on a massage that I’ll enjoy more and will likely have longer results.
