What term describes an excessive sensitivity to painful stimuli?

• A. Allodynia
• B. Hyperalgesia
• C. Viscerosomatic reflex
• D. Fibromyalgia

Answer: (B)

The term "hyperalgesia" describes an exaggerated or heightened sensitivity to painful stimuli. This condition occurs when nociceptive pathways are sensitized, leading to an increased perception of pain in response to stimuli that normally would not be classified as painful or would typically evoke a lesser pain response. Hyperalgesia can result from various factors, including tissue injury, inflammation, or nerve damage, which can alter the way pain signals are processed in the nervous system. This sensitization can occur at both the peripheral and central levels, making the individual more responsive to pain. In contrast, allodynia refers to the phenomenon where typically non-painful stimuli are perceived as painful, but it is not characterized by an exaggerated response to already painful stimuli. Viscerosomatic reflex involves the interaction between visceral and somatic systems, but it does not specifically relate to sensitivity to pain. Fibromyalgia is a chronic condition characterized by widespread pain and tenderness, but it encompasses a broader range of symptoms beyond just increased pain sensitivity. Therefore, hyperalgesia is the most appropriate term for excessive sensitivity to painful stimuli.
