A sprain occurs when the ligaments that hold together the
bones in the ankle are suddenly stretched or torn. With care,
the sprain should heal in 4 to 6 weeks.
Causes
Most sprained ankles result from
a sudden wrench. Some common causes are tripping or bending
your ankle the wrong way.
Signs/Symptoms
Typically, you'll have pain,
tenderness, swelling, or bruising of the injured ankle. You
also may have trouble moving the ankle.
Care
The doctor may x-ray the ankle.
You'll need to wear a splint or an elastic bandage on the ankle
until it heals.
WHAT YOU SHOULD DO
Put ice on the injury for 15 to 20 minutes each hour
for the first 1 or 2 days. Put the ice in a plastic bag and
place a towel between the bag of ice and your
skin.
After the first 1 or 2 days, you may put heat on the
injury for the next 48 hours to help relieve the pain.
Apply the heat for 15 to 20 minutes every hour. You may use
a heating pad (set on low), a whirlpool bath, or warm,
moist towels.
For 48 hours, keep your foot lifted above the level
of your heart whenever possible. This will reduce pain and
swelling.
Activity:
Stay off your feet for 24 hours. You can then begin
to slowly walk more on the injured ankle as the pain
allows.
You may walk on your ankle until it begins to hurt
too much to continue.
Use crutches or a cane until you can stand on your
ankle without having pain.
If you have a plaster splint:
Wear it until your doctor says you may take it off
or until your follow-up visit.
Do not push or lean on it or it may
break.
Do not get it wet. You may take it off to take a
shower.
If you have an air splint:
You may blow more air in it or take some out to
make it more comfortable.
You may take it off at night and when
bathing.
You may have been given an elastic bandage (ace wrap)
to use either alone or with a plaster splint. If your foot
or ankle feels numb or tingly, the bandage is too tight.
You can rewrap it to make it
comfortable.
You may take over-the-counter medications such as
acetaminophen or ibuprofen to help ease the
pain.
Call Your Doctor If...
Your bruising, swelling, or pain is getting
worse.
Your toes below the injury are cold when you touch
them, feel numb, or turn blue or grey.
