Anterior Cutaneous Nerve Entrapment Syndrome (ACNES) is a condition characterized by chronic abdominal pain caused by entrapment or irritation of the anterior cutaneous branches of the lower thoracic intercostal nerves. This condition is often underdiagnosed and can significantly impact a person's quality of life. The symptoms of ACNES can vary in intensity and location, but they typically manifest as:
The most prominent symptom of ACNES is chronic abdominal pain. The pain is usually localized to a specific area of the abdomen, often described as a sharp, stabbing, or burning sensation. The pain may worsen with movement, physical activity, or pressure on the affected area.
ACNES is characterized by the presence of tender trigger points, which are specific areas on the abdomen that are hypersensitive to touch. These trigger points are usually located along the course of the intercostal nerves and can be identified by palpation.
Some individuals with ACNES may experience altered sensation in the affected area. This can include numbness, tingling, or a pins-and-needles sensation. The altered sensation may be intermittent or constant.
In some cases, ACNES can cause localized muscle twitching or fasciculations in the abdominal wall. These involuntary muscle contractions may be visible or palpable and can contribute to the discomfort experienced by individuals with ACNES.
The pain associated with ACNES can be aggravated by certain activities or movements. Common triggers include bending, twisting, coughing, sneezing, or any action that puts strain on the abdominal muscles. The pain may also worsen after prolonged periods of sitting or standing.
It is important to note that ACNES is a diagnosis of exclusion, meaning that other potential causes of abdominal pain should be ruled out before considering ACNES. This may involve various diagnostic tests, such as imaging studies, blood tests, or gastrointestinal evaluations.
Early recognition and accurate diagnosis of ACNES are crucial for effective management and relief of symptoms. If you are experiencing chronic abdominal pain or suspect you may have ACNES, it is recommended to consult with a healthcare professional who can evaluate your symptoms, perform a thorough examination, and determine the most appropriate course of treatment.
