do not put anything inside the cast. this could irritate the skin with small micro-cuts which can lead to an infection. do not use talc or creams inside a plaster cast. these become gritty when mixed with sweat which could also irritate the skin and cause an allergy or infection. raise your arm or leg up above chest level for about 1 hour. this can help reduce the swelling and cool the area which would decrease the itch. if it is too intense talk with your pharmacist about using an oral antihistamine for the itching. be cautious about drug-drug interactions or drowsiness. if the itching is still too intense check with you doctor about recasting the area.
