Do the needles hurt?

The needles are only about the width of a human hair and are solid and flexible. They do not resemble hypodermic needles in design or feeling.
Different acupuncture points elicit different sensations and vary from person to person.
Most people find the needles are virtually painless. Some describe the feeling as aching, warmth, pressure, tingling, or electricity.
Many describe the feeling as different but not necessarily unpleasant.
