Chiropratic can help with pain, but not for the claimed reasons. Studies show it's as efficacious as massage therapy. I believe the same is true of cupping. Insurers increasingly cover these sorts of therapies, and primary's increasingly prescribe them, because they're cheaper than a real doctor's time, especially a specialist's, and the patient is more likely to feel better than if they were subjected to a long diagnostic gauntlet with an inconclusive end.
