What is a Trigger point injection (TPI) Trigger point injection (TPI) may be an option for treating pain
If you have neck, arm, low back, or leg pain (sciatica) stemming from inflammation of the facet joints you may benefit from a facet injection. Typically, it is recommended for those who fail to respond to other conservative treatments, such as oral anti-inflammatory medication, rest, back braces or physical therapy. The doctor may wish to perform the injection as a diagnostic test to determine if the facet joint is causing your pain. Facet injections may be helpful in treating inflamed facet joints caused by:Spinal stenosis: A narrowing of the spinal canal and nerve root canal can cause back and leg pain, especially when walking. Spondylolysis: A weakness or fracture between the upper and lower facets of a vertebra. If the vertebra slips forward (spondylolisthesis), it can compress the nerve roots causing pain. Sciatica: Pain that courses along the sciatic nerve in the buttocks and down the legs. It is usually caused by compression of the 5th lumbar or 1st sacral spinal nerves. Herniated disc: The gel-like material within the disc can bulge or rupture through a weak area in the surrounding wall (annulus). Irritation, pain, and swelling occur when this material squeezes out and comes in contact with a spinal nerve. Arthritis: Joint inflammation caused by degeneration of the cartilage; causes pain, swelling, redness, and restricted movement. Postoperative pain: Acute pain following discectomy or spinal decompression caused by disruption of the facet joint or spine muscles.
