Pruritus is just a big word for when your skin feels itchy! It's usually caused by something that irritates your skin, like an insect bite, dry skin, or an allergic reaction to something you touched or ate. When you scratch the itchy spot, it feels good at first, but it can actually make the itch worse and cause more irritation. That's why it's important to use things like lotion, creams, or medicine to soothe the itchy area instead of scratching it. If the itch persists or is very bad, it's important to talk to your doctor or a dermatologist for help.
