Trigger Point Injection


Trigger point injections are used to treat pain related to muscle spasms. Muscle spasm is an extremely common cause of acute and chronic neck and back pain. Spasms often emerge as painful “knots” within the muscles. The muscles of the neck and back can be so uncomfortable that they also restrict the range of motion. In addition to physical therapy, trigger point injections are also used to help reduce the inflammation and irritation within the muscle.

Before the Procedure

  • If taking aspirin or anti-inflammatory medications daily, stop these medications at least three days before the injection.

During the Procedure

  • The trigger point injection is usually performed in the physician’s clinic.
  • The skin in the area of the injection is cleaned.
  • The skin may be numbed with a local anesthetic.
  • A small needle is inserted into the muscle causing the spasm-related pain (a steroid is sometimes injected also).
  • A local anesthetic is injected into the muscle.
  • The procedure usually takes about 30 minutes.

After the Procedure

  • You will be able to leave the clinic after the injection.
  • Soreness in the area of the injection may be experienced for 24 to 48 hours after the injection.
  • Typically, patients are prescribed to participate in an active physical rehabilitation program after the injection.
