Anterior Cutaneous Nerve Entrapment Syndrome (ACNES) is a condition characterized by chronic abdominal pain caused by entrapment or irritation of the anterior cutaneous nerves in the abdominal wall. It is often underdiagnosed and misdiagnosed due to its similarity to other abdominal conditions.
The most common symptom of ACNES is localized abdominal pain. The pain is typically described as sharp, stabbing, or burning and is usually confined to a small area on the abdominal wall. The pain may worsen with movement, coughing, or deep breathing. It is important to note that the pain does not radiate to other areas of the body.
ACNES pain is often triggered by specific movements or activities. Activities that involve repetitive or prolonged bending, twisting, or stretching of the abdominal muscles can exacerbate the pain. Patients may notice that certain positions or actions consistently provoke the discomfort.
Physical examination is crucial in diagnosing ACNES. A healthcare professional will perform a thorough examination of the abdomen, focusing on the area of pain. The presence of tender points along the course of the anterior cutaneous nerves is a key diagnostic finding. These tender points are usually located in the midline of the abdomen, between the navel and the lower rib cage.
Additional diagnostic tests may be ordered to rule out other conditions. These may include blood tests, imaging studies (such as ultrasound or MRI), and nerve blocks. However, it is important to note that these tests are often normal in ACNES, making the physical examination findings crucial for diagnosis.
Once diagnosed, treatment for ACNES focuses on relieving pain and improving quality of life. This can be achieved through a combination of conservative measures and medical interventions. Conservative measures include physical therapy to strengthen the abdominal muscles and improve posture, as well as lifestyle modifications to avoid activities that trigger the pain. Medical interventions may include nerve blocks to provide temporary pain relief and, in some cases, surgical decompression of the entrapped nerves.
If you are experiencing chronic abdominal pain that fits the description provided, it is important to consult with a healthcare professional. They will be able to evaluate your symptoms, perform a physical examination, and determine if ACNES is the underlying cause of your pain.
