According to the theory, Qi permeates the human body, influencing the mental and physical wellbeing of everyone. It travels through the body via special pathways, known as meridians, but, if these become blocked for any reason, then the balance of Yin and Yang is disturbed, leading (so the theory holds) to illness.
To unblock the meridians, special needles are inserted into the skin where the pathways come to the surface, a treatment known as acupuncture (a related discipline, known as acupressure, uses massage to bring about the same effect).
Whether you subscribe to the ancient theory or not, acupuncture might be able to relieve some of the symptoms of back pain. Unfortunately, it cannot treat the underlying causes.
Acupuncture is not an invalid treatment, but it will only work for relatively mild back pain. It will not treat the underlying cause.
Approximately: £30-40 per session.
A number of sessions are required to reduce the symptoms.
