How to scratch an itch in a cast

Updated November 21, 2016

Casts are applied to broken bones to immobilise the breakage and prevent further injury. Casts can also be used to help torn ligaments heal. Healing can take weeks to more than a month depending on the severity of your injury. A cast lays upon your skin; moisture develops within your cast, which can lead to itching. Avoid placing any item down your cast to alleviate the itching. Using pointy objects to scratch at your skin can cause skin abrasions, leading to infections, notes Family Doctor.

Put your hair dryer on its coolest setting, recommends KidsHealth. Point your hair dryer down between the cast and your skin, toward the affected area. Alternatively, you can purchase comfort sprays specifically designed for casts at your local grocery store. These sprays deliver a blast of cool air to stop itching.

Tap your cast gently. The tapping creates a vibration, which can stop the itching.

Use an ice pack wrapped in a hand towel. Place the ice pack on the affected site, so you can feel the cold penetrate your cast. Leave the ice pack on your cast until the itching stops.

Take an antihistamine. An over-the-counter antihistamine can control your symptoms. Follow the manufacturer's dosing recommendations.

Warning

Don't use the hot setting on your hair dryer. The heat will cause more moisture to develop. Avoid using powders, such as baby powder to alleviate itching. This creates chaffing of your skin. Consult with your doctor if the itching continues.
