So the pain is "referred to" the related dermatomes of the same spinal segment. [3] Viruses that lie dormant in nerve ganglia (e.g. varicella zoster virus, which causes both chickenpox and shingles), often cause either pain, rash or both in a pattern defined by a dermatome (a zosteriform pattern). However, the symptoms may not appear across the ...
Referred pain, also called reflective pain, [1] is pain perceived at a location other than the site of the painful stimulus.An example is the case of angina pectoris brought on by a myocardial infarction (heart attack), where pain is often felt in the left side of neck, left shoulder, and back rather than in the thorax (chest), the site of the injury.
Radicular pain, or radiculitis (from the Latin: radicula, lit. 'small root'), is pain "radiated" along the dermatome (sensory distribution) of a nerve due to inflammation or other irritation of the nerve root ( radiculopathy ) at its connection to the spinal column . [ 1 ]
The peripheral nervous system (PNS) is divided into the somatic nervous system, the autonomic nervous system, and the enteric nervous system.However, it is the somatic nervous system, responsible for body movement and the reception of external stimuli, which allows one to understand how cutaneous innervation is made possible by the action of specific sensory fibers located on the skin, as well ...
Typically, the nerve pain (neuralgia) is confined to an area of skin innervated by a single sensory nerve, which is known as a dermatome. PHN is defined as dermatomal nerve pain that persists for more than 90 days after an outbreak of herpes zoster affecting the same dermatome.
Dissociated sensory loss is a pattern of neurological damage caused by a lesion to a single tract in the spinal cord which involves preservation of fine touch and proprioception with selective loss of pain and temperature. Understanding the mechanisms behind these selective lesions requires a brief discussion of the anatomy involved.

Kehr's sign is a classic example of referred pain: irritation of the diaphragm is signaled by the phrenic nerve as pain in the area above the collarbone. This is because the supraclavicular nerves have the same cervical nerves origin as the phrenic nerve, C3, C4, and C5. [citation needed]
