What are red bumps that are only on your arms and legs and they do not itch?

Red bumps on the arms and legs that do not itch could be a variety of conditions, such as keratosis pilaris, which is a common and harmless skin condition caused by the buildup of keratin in hair follicles. Other possibilities include folliculitis or benign dermatological conditions like cherry angiomas. If the bumps persist or change, it’s best to consult a healthcare professional for an accurate diagnosis and appropriate treatment.
