Paresthesia is a medical term that describes abnormal sensations in the skin, such as tingling, prickling, or numbness. These sensations can occur in various parts of the body, often in the hands, feet, arms, or legs. Paresthesia can be temporary or chronic and may result from pressure on nerves, poor circulation, or underlying health conditions. Common causes of paresthesia include nerve compression, diabetes, and multiple sclerosis. While it can be uncomfortable, paresthesia is usually not serious and often resolves on its own. However, persistent or severe cases may require medical evaluation to determine the underlying cause.
