Detailed explanation-1: -Referred pain is pain perceived at a location other than the site of the painful stimulus/ origin. It is the result of a network of interconnecting sensory nerves, that supplies many different tissues.
Detailed explanation-2: -Where do we feel referred pain? This pain is typically felt deep in muscles, joints, ligaments, and tendons. It is called “referred” because this pain doesn’t occur at the point of injury. Instead, it is felt in a part of the body farther away from the actual injury.
Detailed explanation-3: -Referred shoulder pain is often constant, which means your shoulder will hurt even when you’re resting or not using your arm or shoulder.
Detailed explanation-4: -If your pain is coming from a nerve or a nerve root, you may describe or experience your pain as been a sharp, shooting, or lightning like pain. Muscular pain may present as a dull ache, whereas bone may present as a nagging, deep, and dull pain.
Detailed explanation-5: -The basis of the theory is that a dorsal horn neuron has convergent input from two different body regions. Because of the convergence, thalamic neurons cannot localize the origin of the dorsal horn activation. Basically, the referral of pain is a mislocalization of pain.
