#paresthesia

• Acanthesthesia — A form of paresthesia or subjective disturbance of tactile and painful sensitivity, characterized by a false, spontaneous, and unpleasant sensation of pinpricks or thorn-like pricks on the skin, occurring in the absence of any external mechanical stimulus. This neurological symptom is typically associated with damage to peripheral nerve fibers, being encountered in neuropathies, radiculopathies, or lesions of the sensory pathways in the spinal cord.
• Acrodynia — A complex clinical syndrome characterized by intense pain, erythema, swelling, paresthesia, and desquamation of the hands and feet, often accompanied by severe neuropsychiatric disorders and tachycardia due to mercury poisoning.
• Acroparesthesia — A subjective sensory disorder, episodic or permanent, manifested by abnormal sensations of numbness, tingling, prickling, or burning localized exclusively in the distal extremities of the body (hands and feet). This structural neurological phenomenon reflects irritation or compression of peripheral nerve fibers, serving as a cardinal symptom in carpal tunnel syndrome, metabolic peripheral neuropathies (such as diabetic neuropathy), or functional vasomotor disorders.
• Algoparesthesia — A complex neurological symptom characterized by the simultaneous association of a paresthesia (abnormal sensations such as numbness, tingling, or burning) with a distinct and persistent localized pain sensation. This clinical manifestation occurs due to injury, irritation, or compression of peripheral nerve fibers.
• Numbness — A transient pathological or physiological state characterized by the partial or total loss of tactile sensitivity and voluntary mobility in a specific region of the body, often associated with tingling or prickling sensations. This phenomenon shares characteristics with paresthesia and occurs due to mechanical compression of peripheral nerves, poor blood circulation, or as a symptom of neurological disorders.
• Growing numb — The act of growing numb and its result; the physiological or pathological process through which a limb or body region temporarily loses tactile sensitivity and mobility. In a neurophysiological sense, it represents the transient blockage of nerve impulse transmission, while figuratively it indicates a state of stagnation, inactivity, torpor, or a decrease in the intensity of activities or feelings.
• Numb — Having undergone the process of growing numb; a bodily limb or cutaneous tissue that has temporarily or permanently lost its tactile sensitivity and voluntary motility due to mechanical pressure, cold, or a neurological condition. Figuratively, it describes a person or a psychic faculty devoid of energy, apathetic, torpid, or inert.
