Abdominal wall pain (AWP) is a common and underrecognized cause of chronic abdominal pain. The etiology of AWP varies. History and physical examination are critical to an accurate diagnosis of AWP. Trigger point injection using either a corticosteroid, a local anesthetic, or a combination of both often gives relief of pain and is of diagnostic and therapeutic value. Increased awareness of AWP as a cause of chronic, nonvisceral abdominal pain can prevent fruitless searches for intra-abdominal pathology and reduce medical costs.
