Compare and contrast the mechanism underlying two theories which seek to explain our perception of referred pain. Describe a scenario where knowledge of common sites for pain referral can be useful in clinical practices .

What will be an ideal response


Answer: Referred pain: pain that is perceived or felt at an area distant from the original site of injury /painful stimulus. Two mechanisms that underlie this phenomenon are:

A clinical scenario to demonstrate this phenomenon is: referred pain of acute cholecystitis to the shoulder- acute cholecystitis is the inflammation of gallbladder and when the gallbladder is distended, it irritates the phrenic nerve. The phrenic nerve is part of the cervical plexus which gives rise to many nerves innervating the arm and shoulder. Therefore any irritation of the phrenic nerve is also felt in the shoulder.
