why would that worry you?
wouldn't you rather have your mom explore non-invasive alternatives to drugs and surgery?
As long as she doesn't go to a high-volume chiropractor and sees one that uses other modalities in addition to just pure adjustments nothing but good should come of it - kinda like going to an MD that doesn't just prescribe meds, a PT that only demonstates exercises, or naturopath that only reccomends vitamin supplements.
i still have 7.5 more quarters to go, so I'm "dangerous" to give specific advice on what she should do, but it sounds like she has some sort of imbalance (skeletal, muscular, posture, etc...) that is setting off a chain rxn of events that are causing her problems. could be as simple as one leg may be too short or her pelvis needs and adjustment...or compicated and none of them are related and need to be addressed individually. humans are complicated and no one can actually claim to know what is really wrong with anyone. all you can do is expirement and go with what make you feel better- that;s the bottom line. whatever works. shit, she could go to a hypnotherapist and possible have her problems work. sometime these things just happen for unknown reasons, and have a natural history of just working themselves out.
