Trigger Point Injection

Trigger points are hyper-irritable foci in the myofascia associated with tight muscle bands. They are located by deep palpation of the affected muscle to cause localized or referred pain. These injections are in conjunction with a rehabilitative program to restore normal muscle flexibility, strength and function. Trigger points may also respond to stretching, correction of posture and application of heat or cold packs.


When you arrive, a nurse will obtain a description of your pain and how you are managing daily activities. Your blood pressure, pulse, temperature and weight will be recorded. Medications, allergies and a brief health history will be reviewed. It is important to let the nurse know if you have allergies to medications and latex or if you have diabetes.

After discussing treatment with your physician and signing procedural consent, you will be helped onto the stretcher. Your skin will be cleansed with antiseptic and the physician will inject the medication into the areas of intense pain to relax the muscle spasms and improve blood flow to the area. The procedure will take less than a minute.

For your comfort, please plan to stay with us about 15 to 20 minutes. A nurse will be available to answer any questions you might have and to review discharge instructions and follow-up care.

When you go home

  • Activities: Rest and avoid activities that might aggravate your pain. You can usually return to work and exercising on the next day.
  • Pain: Ice on the injection site and taking your regular pain medications will help with any discomfort. Some patients initially experience more pain after the injection when the anesthetic wears off because the steroid can be irritating to the nerves.
  • Follow-up: Make an appointment for follow up or to repeat the injection as needed.

Many patients will have pain relief after the first or second injection. Some patients will need three injections, don’t be discouraged! Talk with your physician.
