Acupuncture needles are very fine, flexible needles, no bigger around than the width of a human hair or piece of thread. The insertion of the needle is very gentle and produces little or no sensation at all. When the needle makes contact with your Chi, you may feel a “Chi” sensation such as warmth, expansion or heaviness. These are good sensations and a sign that the body is responding to the treatment. Most first time patients are surprised how comfortable and relaxed they feel during their treatment.
