What is referred pain?

What is referred pain?

• A. Type of visceral pain that originates from an organ but is felt in a different part of the body
• B. Pain that is felt at the same location as the organ
• C. Pain due to skin nerves
• D. Pain that occurs only at night

Answer: (A)

Referred pain is when pain from an internal organ is felt in a part of the body away from that organ. This happens because nerves from the organ and from a skin region converge on the same spinal cord pathways, so the brain misinterprets the visceral signal as arising from the skin area. That’s why heart or stomach issues can present as pain elsewhere, like in the chest, arm, jaw, or shoulder, rather than right over the organ. The other descriptions don’t fit: pain at the organ’s location would be localized visceral pain, pain from skin nerves is somatic, and pain that occurs only at night isn’t about the site of origin.
