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.
Third, watch for cracks. Now, your cast may have cuts or cracks in it when it's put on. Doctors sometimes make tiny cuts in the side. This allows room for possible swelling. Many times your body will swell near the broken bone.
