What is a NOT common sign of an abdominal injury?

Frequent headaches are not a common sign of an abdominal injury. Abdominal injuries typically manifest through physical signs and symptoms directly related to the abdomen or the surrounding areas. These can include a rigid abdomen, pale or ashen skin that may be moist due to shock or internal bleeding, and severe pain in the abdominal region itself.

In contrast, headaches are not typically associated with abdominal trauma and can arise from many other unrelated conditions. Therefore, identifying a headache as a symptom would not align with the expected presentations of an injuries to the abdomen. Understanding the specific signs associated with abdominal trauma is critical, as it helps in recognizing the need for prompt medical attention and appropriate interventions for those injuries.
