What does the term paresthesia describe?

The term paresthesia refers specifically to abnormal sensations in the body, such as tingling, prickling, numbness, or a "pins and needles" feeling. These sensations often occur without any clear physical stimulus and can manifest in various parts of the body, commonly seen in conditions affecting the nerves or circulation. For instance, paresthesia may be experienced if a nerve is compressed, often due to pressure on the limb, or may arise from conditions such as diabetes, multiple sclerosis, or injuries. Recognizing paresthesia is crucial as it can indicate underlying health issues that may need further investigation or intervention.
