What Will My Limb Look Like?
Don't be alarmed, but there's a decent chance your limb might look a little odd when the cast comes off. Your skin might look dry, scaly, flaky, or pale, and the hair on your limb might seem darker and thicker than usual. Your limb might even smell a little bit (after all, it's been in a cast and not washed for a while!). All these changes are normal. They should clear up fairly quickly so there's no need to worry about them.
The muscles of your limb will likely appear smaller and weaker (what doctors call "atrophied") because you haven't been using them. This is normal, too, but it will take a little longer for your muscles to get back to their original state than your skin. You'll need to take it easy and limit your activities during this time.
What Should I Do When I Get Home?
You may be tempted to scrub or scratch all the dead skin off your limb the moment you get home. Resist the urge. Your skin is going to be very sensitive for the next few days and you'll need to treat it delicately. Instead of rubbing, scrubbing, or scratching your skin, gently wash it with mild soap and soft cloth or gauze pads.
If you had an open wound when your limb was broken or fractured, your skin may have scabs on it when it's removed from the cast. Don't scratch the scabs as this could damage the skin and possibly lead to an infection. If there's still an open wound, follow your doctor's instructions on how to take care of it.
If your limb was in a cast for 3 weeks or more, soak your skin in warm water for 20 minutes twice a day for the first few days after the cast is removed. Gently rub your skin dry with a soft towel. The key word here is "gentle." Rubbing the skin too hard can damage the new skin.
After the support provided by the cast is gone, people often notice stiffness, pain, and swelling in the limb. Be sure to support your limb as it continues to heal, and move gradually back into using it. Start with small, easy movements and work your way up to using the limb fully.
Keep your skin soft and help speed the healing process by applying lotion after you clean the area where the cast was. This will also help stop itching. Choose a fragrance-free lotion because perfumes can irritate skin that's delicate or sensitive from being in a cast. Lotions made with cocoa butter work particularly well.
If you've just had a cast removed from your leg, avoid shaving the hair on your leg for about 3 days after the cast comes off to give your skin time to recover.
