Acupuncture I have been informed that acupuncture is a generally safe method of treatment, but, as with all types if healthcare interventions, there are some risks to care, including, but not limited to: bruising, bleeding, puffiness, itching, warmth pain; numbness or tingling near the needling sites that may last a few days; and dizziness or fainting. Burns, blistering and/or scarring are a potential risk of moxibustion and cupping, or when treatment involves the use of heat lamps. Bruising is a common side effect of cupping. Unusual risks of acupuncture include nerve damage, damage to deeper structures and organ puncture, including lung puncture (pneumothorax). Infection is another possible risk, although the clinic uses sterile disposable needles and maintains a clean and safe environment.
