Prickling is a sensation often described as a slight, sharp feeling on the skin. It can occur due to various reasons, such as pressure, irritation, or the presence of certain substances. This sensation is commonly associated with conditions like pins and needles or nerve irritation, where the nerves send signals to the brain indicating discomfort. The prickling sensation can also be a response to environmental factors, such as exposure to cold temperatures or contact with stinging plants like nettles. In some cases, it may indicate an underlying medical condition, so persistent or severe prickling should be evaluated by a healthcare professional.
