Acupuncture is a gentle therapy, designed to help bring your body's mind-body energy (called "chi") back into sync. People often find this over 5,000-year health care practice so relaxing that they fall asleep during therapy with the needles still in place!
Unlike hypodermic hollow needles, or "shots," acupuncture needles are extremely thin, about the width of a hair. They are made of stainless steel and are very flexible. Insertion of these needles is often painless, though the sensation varies among individuals. Once the needles are in place there is no pain at all.
Acupuncture needles are all sterile and packaged separately. The ones you receive will be used only on you, during your individual therapy and then discarded.
