The term 'prickly sensation' can be described by two crossword solutions: TINGLE (6 letters) and ITCH (4 letters). Tingling is a sensation of pins and needles, often caused by a lack of blood flow to an area of the body. Itching is a feeling of irritation or discomfort on the skin that can be caused by a variety of factors, such as allergies, dry skin, or insect bites. Both sensations are usually temporary and can be relieved with topical treatments.
