Pins and needles is the layman’s term for the medical diagnoses of Paresthesia. Paresthesia is described as a tingling or prickly feeling of the skin. This sensation is most felt and refereed to when one assumes that a body part, usually a limb, has fallen asleep. While it is true that the feeling of pins usually subsides after a short period of time; research has shown it is also a symptom / warning sign of many illnesses. If you have this feeling, you are advised to research the specific area; as Paresthesia is different depending on its location and cause. Should you experience Paresthesia (pins and needles pain) for an extended period of time, it is vital that you contact a medical professional as soon as possible.
