SN instructed patient about cast care: keep the cast clean and avoid getting dirt or sand inside the cast. Do not apply powder or lotion on or near the cast. Cover the cast when eating, do not place anything inside the cast, even for itchy areas. Sticking items inside the cast can injure the skin and lead to infection. Using a hair dryer on the cool setting may help soothe itching, do not pull the padding out from inside your cast.
