Not everyone who says they do acupuncture can offer you all the benefits of traditional acupuncture.
Some healthcare professionals use a reduced form of acupuncture to treat simple conditions. You will only experience the complete system of acupuncture when you see a traditional acupuncturist.
For pain treatments I frequently use Dr Tan style acupuncture, which will use points far from the area of pain. For example to treat headaches I may use the knee, for shoulder pain I may use the ankle and calf. However each patient is different, and your treatment plan is individual to you and where exactly you experience pain.
