The Obliques - Trigger Point Anatomy
Trigger Points in the Obliques can be the Cause of Stomach, Chest, or Groin Pain
The posterior fibers of the external oblique are usually overlapped by the latissimus dorsi, but in some cases there is a space between the two, known as the lumbar triangle, situated just above the iliac crest.
The lumbar triangle is a weak point in the abdominal wall.
