The person who treats you is called an acupuncturist. He’ll swab each area with alcohol before tapping a very thin needle into the site. The number of needles you’ll get, where they’re placed, and how deeply they’re inserted depends upon your particular case.
The needles will stay in place for several minutes to an hour. The acupuncturist may adjust, warm, or electrically energize them to intensify the effect. You may feel some tingling if electricity is used. It should be mild, and you can ask your acupuncturist to dial it down at any time.
You may need to get more than one session.
