What does the term 'paresthesia' refer to?

The term 'paresthesia' refers specifically to abnormal sensations such as tingling, prickling, or numbness that occur without an apparent physical cause. This can manifest in various parts of the body and is often described by patients as having a “pins and needles” feeling. Paresthesia can result from several factors, including nerve damage, compression of nerves, or certain medical conditions.

In contrast, fluid retention in the tissues, loss of sensation in the extremities, and managing anxiety through relaxation techniques refer to different medical conditions or approaches not associated with the sensations described by paresthesia. Understanding the distinction helps clarify what paresthesia signifies in clinical contexts, such as neurological examinations or assessments of nerve function.
