Anterior cutaneous nerve entrapment syndrome is a condition that causes chronic pain of the abdominal wall. Around 20% of patients with chronic abdominal pain have abdominal wall pain, which is often caused by ACNES. The primary symptom of anterior cutaneous nerve entrapment syndrome is a sharp stabbing pain that typically increases with exercise and the use of the abdominal muscles. A telltale sign that a patient may have ACNES is that the reoccurring pain is always in the same spot.
This painful condition typically affects young women, but it can occur at any age. History of trauma, pregnancy and delivery, or abdominal surgery is sometimes present. A substantial number of ACNES patients report previous visits to the ER with acute pain. Treatment will usually consist of injections of local anesthetic, and in some severe cases, surgery is needed.
