What does a sprained ankle mean?

A sprained ankle occurs when the foot or ankle is forced inwards or outwards past its normal range of motion. This may result in some of the ligaments, which surround and support the ankle, being stretched or torn. There will be tenderness around the injury and pain will be made worse by movements and walking. It may take around six weeks to fully recover.

What to expect

For the first and second week, you may have pain when you walk. It is normal for the ankle to swell up either immediately or later. Bruising may appear after a few days. The swelling and bruising may last several weeks. This is normal and nothing to worry about. If you are unable to put any weight on your ankle, you will be given crutches.

How do I help the ankle sprain to heal?

It is very important to put weight on the foot as soon as the severe pain is easing, as this helps with healing. This will be quite painful at first, as the tissues will feel very tight. You will also find it more painful first thing in the morning and after resting the ankle for a long time.

How can I reduce the swelling?

When you are not on your feet, you should sit with your feet up on a cushion, so that the ankle is higher than the hip. This allows the swelling to drain away.  Over the first two to three days, place an ice pack or a bag of frozen peas on the ankle for 10–15 minutes, four times a day. Before doing this, cover the ankle with a damp cloth or tea towel so that you do not burn the skin.

Will exercises help?

Yes. The muscles and ligaments around the ankle need to be strengthened after an injury. You also need to re-stimulate the nerves that co-ordinate balance to avoid injuring the ankle again.

Why didn’t I have an x-ray?

Clinical research on thousands of patients has shown which findings on examination, safely exclude a broken bone. If x-rays were not ordered for you, this is because the findings of your examination fell into this category.

Exercises

  1. As soon as you get home, you should do the following ankle exercises four times a day for two minutes each. Carry on with them until the ankle movement has returned to normal.

While sitting on a comfortable chair with the ankle elevated.

  • Move your foot up and down 20 times
  • Turn your foot inward and outwards in a twisting motion 20 times
  • Make 20 circles with your foot in each direction
  1. As soon as the symptoms allow and the pain has settled, you should do the following balance exercise four times a day for a further week.

Stand on your injured foot, take the weight off the non-injured foot, hold the knee slightly bent and try to keep your balance for 30 seconds.

Follow up

You are advised to come back to the Emergency Department if:

  • Your pain or ability to walk suddenly becomes worse
