Recent papers, including a review conducted by van Tulder et al., have suggested that there is paucity of information as to the efficacy of acupuncture treatment. However, there has been a significant increase in the use of acupuncture therapy for treatment of various ailments, including lower back pain. Chiropractors, along with other health care professionals, are using acupuncture as an adjunct to their main therapeutic intervention as demonstrated by a recent survey by the Canadian Chiropractic Protective Association (CCPA). However, like many other interventions, including NSAIDs and spinal manipulations, signs of side effects should be monitored when acupuncture treatments are considered. Recent papers have noted such complications as pneumothorax and hepatitis following acupuncture treatments. A case is presented in which a patient, who received previous acupuncture treatments, presented to a chiropractic clinic complaining of low back and leg pain. Early recognition of potential complications after acupuncture treatment may minimize significant impairments and disability.
