Yes, the ice will penetrate through your cast if you leave it on long enough. This will help reduce any swelling and pain. One of the best methods to ice down your cast is to use bags of frozen vegetables.

Can you ice through a cast?

Apply ice.

Loosely wrap an ice pack covered in a thin towel around your child's cast at the level of the injury. Wrapping the ice is important to keep the cast dry. Ice that's packed in a rigid container and touches the cast at only one point won't be as effective.

Should you ice a cast?

Ice your splint or cast—it's fine to do this while your limb is elevated. The best way to ice your injury is with an ice pack, or dry plastic bag filled with ice and wrapped loosely around the cast at the point of injury. Icing is most effective when it covers the surface of the cast.
