Answer :
Final answer:
Abdominal wall tenderness can originate from irritation or inflammation of the muscles in the abdominal wall or from deeper lesions or structures within the abdomen. Patient movement or activities that stress the abdominal muscles can worsen the tenderness.
Explanation:
Abdominal wall tenderness can originate from various sources. One possible source is irritation or inflammation of the muscles in the abdominal wall, such as the external oblique, internal oblique, and transversus abdominis muscles. These muscles can become tender when there is strain or injury, leading to localized pain and tenderness.
Another possible origin of abdominal wall tenderness is deeper lesions or structures within the abdomen. For example, if there is inflammation or infection in an organ like the liver or appendix, the pain can be referred to the abdominal wall, causing tenderness. This is known as referred pain.
When a patient performs certain movements or activities that put stress on the abdominal muscles, the tenderness may persist or worsen. For example, coughing, sneezing, or laughing can cause increased strain on the muscles, leading to increased tenderness.
