Ensure firstly that the Acupuncturist is a Member of ACI and carries full Professional Indemnity Insurance. Your personal rapport with the Acupuncturist is important so try to find somebody with whom you feel comfortable, who understands what you want to achieve from treatment and who will take the time to explain how he/she feels acupuncture can help you. Just like orthodox medicine, acupuncture has its limitations also so ask about previous experience with conditions similar to your own and the signs and symptoms that indicate progress.
Finally confirm that your chosen practitioner uses single use sterile disposable needles only. Leave immediately if the practitioner re-uses needles. All Members of the ACI use only single use sterile disposable needles. Members are also bound by strict Codes of Clinical Practice and Professional Ethics.
