What term refers to an abnormal tactile sensation such as numbness, tingling, or burning?

• A. Hypesthesia
• B. Paresthesia
• C. Allodynia
• D. Hyperesthesia

Answer: (B)

The term that refers to an abnormal tactile sensation such as numbness, tingling, or burning is "paresthesia." This condition specifically describes sensations that are often described as prickling, tingling, or a feeling of "pins and needles." It can occur without an obvious external cause and is frequently associated with nerve dysfunction or irritation.

Paresthesia can be transient, as in the case of a limb "falling asleep," or it can be chronic, indicating underlying health issues that may require medical evaluation. Understanding this term is vital in medical contexts, as it helps healthcare providers assess neurological function and understand patient symptoms better.

The other terms provided relate to different sensory conditions. For instance, hypesthesia refers to reduced sensitivity to stimuli, hyperesthesia indicates increased sensitivity, and allodynia describes pain due to a stimulus that does not normally provoke pain. Each of these terms highlights different aspects of sensory perception, making it clear why paresthesia is the most appropriate choice for abnormal tactile sensations like numbness and tingling.
