Complementary and alternative medicine (CAM) refers to medical practices that are not part of conventional Western medicine. CAM practices can be used together with or instead of conventional treatments. CAM includes manipulative practices like chiropractic and massage therapy that involve manipulating the body; biologically based practices using herbs, vitamins, and supplements; mind-body practices like meditation, yoga, and hypnosis; and energy medicine practices like acupuncture. Research suggests some CAM practices can help treat pain, but their effectiveness depends on the individual and condition. It is important to talk to a health care provider before starting any CAM treatment.
