ANATOMY

Detailed explanation-1: -Referred pain is when the pain you feel in one part of your body is actually caused by pain or injury in another part of your body. 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.

Detailed explanation-2: -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-3: -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-4: -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.
