Paresthesia refers to which type of sensation?

Paresthesia is indeed defined as an abnormal tactile sensation. It encompasses feelings such as tingling, prickling, or a "pins and needles" sensation that occur without an obvious external cause. This condition can arise from various medical issues, such as nerve compression, neurological disorders, or even as a side effect of certain medications. Understanding this term is crucial for recognizing and assessing sensory abnormalities in patients. The other options describe different sensations or conditions that do not accurately capture the nature of paresthesia, which specifically pertains to abnormal tactile sensations rather than pain, normal feeling, or heightened sensitivity.
