The rectus abdominis has two distinct pain patterns: one at the level of the xiphoid process, spreading bilaterally across the middle back, and the other at the level between the umbilicus and the inguinal ligament, spreading pain into the sacroiliac joint and lower back.
Rectus abdominis myofascial trigger points can also cause chest pain, heartburn, belching, diarrhea, dysmenorrhea, and appendicitis (McBurney’s point).
