Kehr's sign is associated with which type of pain?

Kehr's sign is defined as the phenomenon of referred pain occurring in the left shoulder and arm, primarily as an indication of splenic injury or irritation of the diaphragm. This occurs because the phrenic nerve, which innervates the diaphragm, also refers sensations to areas of the neck and shoulder due to their shared neural pathways. Therefore, the presence of pain in the left shoulder and arm can indicate an underlying condition affecting the spleen or related structures, making it an important clinical sign to recognize in the assessment of abdominal injuries.

The other types of pain described in the choices do not align with Kehr's sign and instead may point to other conditions or injuries that would require different attention and evaluation in a medical setting.
