Trigger Point Injections(TPI)

TPI's are used to treat a number of conditions including:

  • Tension headaches
  • Poor posture
  • Myofascial pain
  • Fibromyalgia
  • Chronic tension from stress
  • myofascial pain syndrome
  • Traumatic or overuse (repetitive motion) injury


Things to know:

  • Trigger points are focal areas of muscle spasm often located in the upper back and shoulder areas.

  • A trigger point injection involves the injection of medication directly into the trigger point.

About Trigger Point Therapy

TPI is another viable regenerative injection therapy option for treating pain.  TPI treats painful areas of muscle that contain trigger points or knots of muscle. These trigger points or knots of muscle is the result of when muscles do not relax.


TPI can provide relief to areas of the muscles that are painful to touch. Generally, a small amount of local anesthetic (numbing medication) is injected into the painful site. The local anesthetic will not only numb the area, but decrease the muscle spasm and relieve the pain.

What is a trigger point?

Trigger points are focal areas of spasm and inflammation in skeletal muscle. The rhomboid and trapezius back muscles, located in the upper back and behind the shoulder areas, are a common site of trigger points. Trigger points in these areas can cause neck pain, shoulder pain, and headache. In addition to the upper spine, trigger points can also occur in the low back or less commonly in the extremities


Often there is a palpable nodule in the muscle where the trigger point is located. The area is tender, and frequently when pushed, pain radiates from the trigger point itself to an area around the trigger point. Trigger points commonly accompany chronic musculoskeletal disorders such as fibromyalgia, myofascial pain syndrome neck pain and low back pain. They may also occur with a tension headache and temporomandibular pain. Acute trauma or repetitive minor injury can lead to the development of trigger points 

There are two types of trigger points:
