Coping with Cast Discomfort: Tips for Managing Pain, Itching, and Infection

If you need to wear a cast for a broken arm, after knee surgery, or for another injury, it's normal to experience some discomfort. The cast keeps your bone or joint immobile so it can heal properly, but it can also cause issues like swelling, itching, and even infection. Here's what you need to know to manage these common cast problems.

Types of Casts

There are two main types of hard casts:

• Plaster cast: Made from plaster of Paris, which hardens when mixed with water. Avoid getting it wet, as this can cause it to dissolve or irritate your skin.

• Fiberglass cast: Made from fiberglass, a lightweight and durable plastic. It's water-resistant, but the padding underneath is not, so it's best to keep it dry.

In some cases, your doctor may recommend a soft cast made of elastic or other flexible material, especially for young children or after surgery.

Managing Swelling

It's normal for your cast to feel snug, especially in the first few days after your injury. This is usually due to swelling. To reduce swelling:

• Elevate the injured limb above your heart using pillows or cushions

• Wiggle your fingers or toes often to prevent stiffness

• Apply an ice pack wrapped in a thin towel to the outside of the cast for 15-30 minutes every few hours

If you're feeling sore or swollen, ask your doctor if over-the-counter pain medications like acetaminophen or ibuprofen can help.

Dealing with Itching

Itching under a cast can be maddening, but resist the urge to stick objects like pencils or rulers inside the cast to scratch. This can break your skin and lead to infection. Instead, try:

• Tapping on the outside of the cast at the site of the itch

• Blowing cool air from a hair dryer around the edges of the cast

• Avoiding applying lotions, oils, deodorant, or powder in or around the cast

Preventing Infection

While some odor is normal after wearing a cast for a while, a foul smell or discharge could indicate a skin infection underneath. Seek treatment right away if you suspect an infection.

When to Call Your Doctor

Contact your doctor if you experience any of the following:

• Fever (higher than 100°F for children or 101°F for adults)

• Numbness, tingling, burning, or stinging in the injured limb

• Worsening pain or swelling

• Cold, pale, or bluish skin

• A crack or soft spots in the cast

• A wet cast that won't dry

• Red or raw skin around the cast

• Difficulty moving fingers or toes

Remember, while wearing a cast can be uncomfortable at times, proper care can help minimize problems and promote healing. If you have any concerns, don't hesitate to reach out to your healthcare provider for guidance.
