"Pins and needles," also known as paresthesia, is a sensation often described as tingling, prickling, or a feeling of numbness. This sensation usually occurs when pressure is applied to nerves, often from sitting or lying in one position for too long. Once the pressure is relieved, normal sensation typically returns. While pins and needles are usually harmless and temporary, they can sometimes indicate underlying health issues, such as nerve damage or circulation problems. If the sensation persists or is accompanied by other symptoms, it is advisable to consult a healthcare professional for further evaluation.
