Acupuncture and dry needling are used by a range of health professionals to treat conditions such as musculoskeletal pain. Treatment occurs both in an outpatient setting and in emergency departments (ED). Acupuncture and dry needling are considered to be relatively safe techniques with a low risk of serious adverse events. We report three cases of traumatic pneumothorax following acupuncture/dry needling that presented to our ED between 2014 and 2016.
