The majority of people who are frightened of needles find that acupuncture needles do not bother them at all. In addition to needles, techniques such as cupping, moxibustion (where a herb is smouldered near the skin to warm joints or muscles) or electro-acupuncture (where a tiny electric current puts a rhythmic pulse through the needles) may be used. These additional treatments are widely used, and are generally experienced as pleasant and relaxing. Most people leave an acupuncture treatment feeling relaxed both mentally and physically.
