The psoas muscle attaches to the sides of the vertebrae in your lower back. It goes down through your abdomen and joins forces with the iliacus muscle, which attaches all along the inner surface of your pelvis. Then as one muscle they pass through your groin and attach to the inner front of the top of your thigh. The job of this muscle (these muscles) is to lift your leg forward. Trigger points in these muscles can cause pain in the abdomen, pelvis, groin, upper thigh, low back and buttock.
Iliopsoas Muscles The iliopsoas muscle is frequently regarded as a single muscle, because it is a blending of two muscles, the psoas major and the iliacus. The "psoas major" is a powerful flexor muscle of the thigh at the hip joint. If both psoas major muscles are fixed from below, they act as important flexors of the trunk on the hip, as in sitting up from a lying-down position. The "psoas minor" is a weak flexor of the trunk and the lumbar spinal column. It is supplied by a branch of the first lumbar nerve. The "iliacus" works with the psoas major as a powerful flexor of the thigh at the hip joint. It joins the psoas in a number of other actions as the "iliopsoas." JEAN (from PA)

Does anyone else here have adhesions involving the
