Choose someone that feels right and trust your instinct. There are a few things to be aware of when choosing an acupuncturist:
What is the practitioners level of acupuncture specific training? In the UK anybody can call themselves an acupuncturist or perform acupuncture regardless of their level of training or experience. I completed a four-year degree level training in Acupuncture at the Northern College of Acupuncture. I am a member of the British Acupuncture Council. The British Acupuncture Council sets the highest standards of education, safe and ethical practice and continuous professional development and is the only register of acupuncturists to be voluntarily accredited with the Professional Standards Authority.
Most importantly, do you feel at ease? Speak with an acupuncturist about your specific well-being issues and ask questions. Do you feel they understand you, can put you at ease and that you can work with them.
