When administered correctly, acupuncture should not hurt. Needles are fine, the same width as a human hair. They are all sterile, single-use and are safely disposed of once removed. The acupuncturist will insert the needles as painlessly as possible. Many people find it calming and relaxing. You may feel a tingling sensation or a dull ache, which is a sign that the body’s Qi has been stimulated. Some people may feel tired afterwards.
