Acupuncture is used mainly to relieve discomfort associated with a variety of diseases and conditions, including:

• Chemotherapy-induced and postoperative nausea and vomiting.
• Dental pain.
• Fibromyalgia.
• Headaches, including tension headaches and migraines.
• Labor pain.
• Lower back pain.
• Neck pain.
• Osteoarthritis.
• Menstrual cramps.
• Respiratory disorders, such as allergic rhinitis.
• Tennis elbow.

The risks of acupuncture are low if you have a competent, certified acupuncture practitioner using sterile needles. Common side effects include soreness and minor bleeding or bruising where the needles were inserted. Single-use, disposable needles are now the practice standard, so the risk of infection is minimal. Not everyone is a good candidate for acupuncture.

Before having acupuncture treatment, be sure to tell the practitioner if you:

• Have a pacemaker. Acupuncture that involves applying mild electrical pulses to the needles may potentially interfere with a pacemaker's operation.
• Are pregnant. Some acupuncture points are thought to stimulate labor, which could result in a premature delivery.

No special preparation is required before acupuncture treatment.

Choosing a practitioner

If you're considering acupuncture, take the same steps you would to choose a doctor:

• Ask people you trust for recommendations.
• Check the practitioner's training and credentials. Most states require that nonphysician acupuncturists pass an exam conducted by the National Certification Commission for Acupuncture and Oriental Medicine.
• Interview the practitioner. Ask what's involved in the treatment, how likely it is to help your condition and how much it will cost.
• Find out whether your insurance covers the treatment.

Tell your doctor that you're considering acupuncture. He or she may be able to tell you about the success rate of using acupuncture for your condition or recommend an acupuncture practitioner.

Each person who performs acupuncture has a unique style, often blending aspects of Eastern and Western approaches to medicine. To determine the type of acupuncture treatment that will help you the most, your practitioner may ask you about your symptoms, behaviors and lifestyle. He or she may also closely examine:

• The parts of your body that are painful.
• The shape, coating and color of your tongue.
• The color of your face.
• The strength, rhythm and quality of the pulse in your wrist.

An acupuncture session may take up to 60 minutes, although some appointments may be much shorter. A common treatment plan for a single complaint would typically involve one or two treatments a week. The number of treatments will depend on the condition being treated and its severity. In general, it's common to receive 6 to 8 treatments.

During the procedure

Acupuncture points are situated in all areas of the body. Sometimes the appropriate points are far removed from the area of your pain. Your acupuncture practitioner will tell you the general site of the planned treatment and whether you need to remove any clothing. A gown, towel or sheet will be provided. You lie on a padded table for the treatment, which involves:

• Needle insertion. Acupuncture needles are inserted to various depths at strategic points on your body. The needles are very thin, so insertion usually causes little discomfort. People often don't feel them inserted at all. A typical treatment uses 5 to 20 needles. You may feel a mild aching sensation when a needle reaches the correct depth.
• Needle manipulation. Your practitioner may gently move or twirl the needles after placement or apply heat or mild electrical pulses to the needles.
• Needle removal. In most cases, the needles remain in place for 10 to 15 minutes while you lie still and relax. There is usually no discomfort when the needles are removed.

After the procedure

Some people feel relaxed and others feel energized after an acupuncture treatment. But not everyone responds to acupuncture. If your symptoms don't begin to improve within a few weeks, acupuncture may not be right for you.

The benefits of acupuncture are sometimes difficult to measure, but many people find it helpful as a means to control a variety of painful conditions.

Acupuncture has few side effects, so it may be worth a try if you're having trouble controlling pain with more-conventional methods.
