Tingling is a sensation often described as a prickling or "pins and needles" feeling in the skin. It can occur in various parts of the body, such as the hands, feet, or face, and is usually temporary. This sensation is often caused by pressure on nerves, which can happen when sitting or lying in one position for too long. In some cases, tingling may indicate an underlying medical condition, such as diabetes or multiple sclerosis. It can also be a side effect of certain medications or a result of anxiety. If tingling persists or is accompanied by other symptoms, it is advisable to consult a healthcare professional.
