Abstract
PAIN is a lesion or disorder of the somatosensory system. The sensory system that produces the conscious feeling of touch, pressure, pain, and temperature is known as the somatosensory system. It is a special complex of neuronal structures in the brain and body (Bouhassira, et al., 2014). All significant organ systems in the vertebrate body are interconnected through the somatosensory system. It comprises of deeper neurons within the central nervous system as well as sensory receptors and neurons in the peripheral nervous system (such as skin, muscle, and organs). The somatosensory systems provide details about the position and movement of our bodily parts (proprioception) through the stimulation of muscles and joints as well as about events in our external environment through touch (i.e., physical contact with skin). The somatosensory systems also keep track of body temperature, the temperature of surroundings and objects outside the body and provide information on stimuli that hurt, itch, or tickle (MacDonald, et al., 2019). A peripheral neuropathy affecting somatosensory system peripheral nerves may be the root cause of a somatosensory deficit, numbness or paresthesia could be the symptoms. The parietal lobe’s postcentral gyrus contains the primary somatosensory region of the human cortex, tasked with processing tactile inputs.
