What is a sprained ankle?

When you twist your foot, you can sprain your foot. This is called a strain or a sprain.
As you sprain your ankle, the ligaments in the outer part of the ankle are under tension. These ligaments can stretch and small tears can occur.
This usually happens during sports activity.

How to recognize it?

  • You feel a sharp pain, usually in the outer part of the ankle.
  • Your ankle swells and may turn blue.
  • Usually, you can still lean on your foot, but you cannot walk normally.

Can’t lean on your foot anymore? So you might have a fracture ankle.

In any case, consult your doctor. If it’s a sprain, your ankle may be:

  • Slightly sprained (slight sprain):
    • In this case, it will take you about 2 weeks to recover;
  • Severe stride:
    • In this case, it will take 6 to 8 weeks to recover.

How is the diagnosis made?

To diagnose a sprained ankle, your doctor

  • ask you questions;
  • examine your ankle;
  • if necessary, request an x-ray of the ankle.
Discussion

Your doctor may ask you the following questions:

  • How and when did you twist your ankle?
  • Could you lean on your foot after the accident?
  • What did you do to relieve the symptoms? For example, did you put on ice or ointment, did you take a painkiller, …?
  • Have you ever sprained your foot before?
  • What medications do you take ? For example, do you take anti coagulants ?
  • What is your job ?
  • Do you exercise regularly?
Physical examination

Your doctor will examine your ankle:

  • He will be particularly attentive to signs that may suggest a crack or a fracture;
  • He will apply a rule (the Ottawa criteria) that allows him to:
    • To assess the risk of fracture and ;
    • Decide whether or not an ankle x-ray is needed.
  • If he finds no signs of a fracture, he may ask you to come back for a consultation a few days later. The pain and swelling will have decreased. This allows for better evaluation.

What can you do ?

First days after the sprain

During the first 3 days (inflammation phase)

  • Let your ankle rest:
    • Do not lean on your ankle unless the symptoms are not too severe;
    • You can temporarily use crutches if the support is too painful.
  • If the pain is severe:
    • It can be useful to:
      • Cool the ankle by applying cold (ice) for 15-20 minutes, 1-3 times a day;
      • Elevate the foot;
      • Take paracetamol and apply anti-inflammatory ointment.
    • You can ask your doctor
      • If you can replace the ointment with a anti-inflammatory, such as ibuprofen or naproxen, if your symptoms do not get better enough;
      • If they think a supportive bandage, band, or splint is helpful for you.
First phase of recovery

During the first phase of recovery (from 4th to 10th day after the sprain), you can try to move the ankle:

  • Stay within the limits of pain;
  • Try to unwind your foot normally;
  • Avoid limping with a stiff foot: it is not good for recovery.
Subsequent recovery phase

During the subsequent recovery phase (from 11th day up to 6 weeks after the sprain):

  • It is absolutely necessary that you train and do exercises at home at home:
    • Your physiotherapist will give you the necessary advice.
  • You may be able to resume your daily activities, depending on the severity of the sprain and the type of work you are doing:
    • This decision is always taken with your doctor, your occupational doctor and, if necessary, your physiotherapist.

After the agreement of your doctor and your physiotherapist, you can gradually resume your sports activities.
