Trigger Point injection therapy is another pain-relief treatment provided by the team of specialists at South Lake Medical Center in Pasadena, California. Focused always on providing services designed to promote optimal health and wellness, doctors at South Lake may prescribe Trigger Point Injections to relieve your symptoms and treat the underlying cause.

What’s a Trigger Point?

A Trigger Point is a small, painful area of knotted skeletal muscle that inflames the nerves surrounding the knot. This causes pain at the site and may result in pain traveling along the nerve to other areas in the body. Sometimes felt under the skin as a bump, palpating a Trigger Point may produce radiating pain that moves out from the site in bands. Trigger Points can interfere with range of motion in the affected area and can cause pain, headaches, stiff neck, and other painful conditions.

How do you get a Trigger Point?

Trigger Points may result from:

  • Prolonged poor posture
  • Activities that repetitively stress specific muscles or muscle groups
  • Acute or chronic injury
  • Sedentary lifestyle
  • Working for prolonged periods at a desk or computer station
  • Sitting in chairs for long periods that lack back support or arm rests

How are Trigger Point Injections performed?

Your doctor first identifies the location of the Trigger Point and cleanses the skin over the site. The doctor then painlessly injects an anti-inflammatory substance blended with anesthetic directly into the painful Trigger Point. All injections are done with precision-guided ultrasound to secure proper placement of the injection with almost 100% accuracy to decompress the nerves, relieving pain. This therapy alleviates the pain, and helps relax the affected area, allowing more movement to occur. Trigger Points may occur in several areas of the body at once, thus your doctor may opt to do several injections during one session. Trigger Point injections are delivered with very thin, small needles that help decrease discomfort. Most patients report little to no pain but may experience some slight soreness at the site as the knot dissipates and the muscle heals.

What else can I do about Trigger Points?

Depending on the underlying cause, correcting posture, increasing exercise, taking breaks from computer or desk work during the day, and making sure your workstation is ergonomically correct may help prevent recurrence of some Trigger Points. Your doctor at South Lake Medical Center, Inc. will do a careful evaluation to determine the cause of your Trigger Points and may recommend physical Rehabilitation, Acupuncture, Chiropractic adjustment, Physiotherapy, Massage, and other treatments to help resolve the underlying issue and to prevent recurrent pain from these painful Trigger Points.
