Your acupuncturist will probably get things started by asking a lot of questions about your personal and family medical history; recent events that might have contributed to your illness; and how you’re responding to various stimuli, such as heat and cold.

During the treatment itself, you’ll sit or lie on a padded table while he or she inserts very fine sterile needles into your skin.

You might feel a small pinprick sensation when the needle is first inserted; once it’s in, you may experience numbness or a tingling sensation that goes away after a few seconds.

Your acupuncturist might also manipulate the needles, apply light electricity to them, or heat them.

Depending on your response and your health problem, you might need just one session or many sessions. Keep in mind, too, that most acupuncturists see needle therapy as just one part of treatment; yours might also suggest herbs, vitamin or mineral supplements, and changes in diet and exercise.

If your acupuncturist recommends an herbal remedy, be sure to mention any other drugs or herbs you’re taking to avoid potentially harmful interactions.

Note, too, that because the government doesn’t regulate herbal products, it’s hard to know exactly what you’re getting (in rare cases, products may be contaminated with undesirable substances).

Also, remember that the NIH evaluation of acupuncture looked only at the effectiveness of needles — not dietary supplements and herbs.
