Dr. MJ Bazos MD,
Why do I need a cast?
You have been given a cast to help your broken
bone or torn ligaments heal. A cast can help keep the injured area from moving
so you can heal faster without risk of repeated injury. How long you'll need to
wear your cast depends on the type of injury you have and how serious it is.
Your doctor may want to check your cast 1 to 3 days after putting it
on to be sure that the cast isn't too tight and that your broken bone or torn
ligament is starting to heal.
Will the broken bone hurt?
Almost all broken bones cause pain. The cast
should relieve some pain by limiting your movements. Your pain should become
less severe each day. Call your doctor immediately if the pain in the casted
area gets worse after the cast has been applied. You should also call your
doctor right away if you have new pain that develops in another area (for
example, pain in your fingers or forearm if you have a wrist or thumb injury, or
pain in your toes or calf if you have an ankle or foot injury).
New pain that you didn't have before the injury
may mean that the cast is too tight. If you have this symptom, raise your cast.
This may reduce pain and swelling. Your doctor will probably want to see you
right away to check the cast.
Is it okay to get the cast wet?
With some fiberglass casts, you can swim and
bathe. However, most casts shouldn't get wet. If you get one of these casts wet,
irritation and infection of the skin could develop. Talk to your doctor about
how to care for your cast.
To avoid getting the cast wet during bathing,
you can put a plastic bag over the cast and hold it with a rubber band. If the
cast does get wet, you may be able to dry out the inside padding with a
blow-dryer. (Use a low setting and blow the air through the outside of the
cast.) Ask your doctor about using a blow-dryer before trying this.
What can I do about itching?
If your skin itches underneath the cast, don't
slip anything inside the cast, since it may damage your skin and you could get
an infection. Instead, try tapping the cast or blowing air from a blow-dryer
down into the cast.
