Introduction
Pain-sensing nerves are generally located under the skin. Pain perception is a normal physiological response of the human body and serves as a defense mechanism against external stimuli. In daily life, avoid excessive fatigue, develop good作息 habits, ensure adequate rest, and refrain from heavy physical labor or high-intensity exercise. If discomfort occurs, seek medical attention promptly to prevent delay in treatment.
Pain-sensing nerves are generally located under the skin. Specific details are as follows:
Pain perception is a normal physiological response of the human body and serves as a defense mechanism against external stimuli. Pain refers to the sensation of excitation generated by nerve cells at a specific site, which is transmitted via reflex arcs to the central nervous system and then through white matter to the cerebral cortex. Pain-sensing nerves are typically situated beneath the skin and can be distributed among the epidermis, dermis, hair follicles, mucous membranes, cornea, and stratified epithelial cells in the oral cavity. Pain points in the skin correspond to free nerve endings, although some pain points are also located within the dermis. Because this layer is relatively superficial, stimulation or touch to the skin easily activates pain receptors and surrounding nerves. If pain-sensing nerves become pathological, they may become more sensitive to local stimuli, potentially causing localized skin pain.
In daily life, avoid excessive fatigue, develop good作息 habits (sleep and rest routines), ensure adequate rest, avoid heavy physical labor, and refrain from high-intensity physical exercise. If discomfort occurs, seek medical attention promptly to prevent delays in diagnosis and treatment.
