Myofascial trigger points in the abdominal muscles are very common. These muscles are responsible for trunk movement and stability, and are engaged in some way during most activities. As a result trigger points will easily form. These knots will often refer pain into the lower or mid back in a horizontal strip. Trigger points in the abdominal muscles are often overlooked as a source of back pain. Once developed, a trigger point won’t release on its own. A therapeutic modality such as trigger point massage is needed to release the tissue.
