Luckily, some casts are also waterproof. This means you can get them wet without ruining the cast. Most of these are made of fiberglass. Also, the padding is not made of cotton. It is made of another waterproof material. With this type of cast you can take a shower or a bath without having to use a plastic bag or sleeve. You might even be able to swim! Be sure to check with your doctor first, though.
Second, never stick anything inside your cast. You could injure the cast or the skin underneath. But the skin under the cast often itches. What should you do? Here's a neat trick -- use a blow-dryer set on "cool." Blow air inside the cast. It really works, and it won't hurt.
