What is a sprain?

A sprain is an injury to the ligaments near a joint. Ligaments are strong bands of tissue that connect one bone to another. They help hold joints together.  A minor sprain means the ligaments may have been overstretched. In more serious sprains the ligament may be partially or completely torn.

What is the treatment?

Protect               Avoid overstretching the joint.

Rest                    For the first 24 hours, when the pain typically gets slightly worse, avoid putting full weight on the affected leg.

Ice                       Either crushed ice or a bag of frozen peas.  Don’t apply ice directly to skin, place it over a tea towel

Compression     Support bandages sometimes work if applied very soon (i.e. minutes) after the  injury.  They are rarely used outside this timeframe as they do not                                work

Elevation            Raise the joint and support it above the level of the heart.

Exercises

These may be uncomfortable at the beginning but will prevent stiffness and weakness.

  1. Pull the foot up and then point the foot down.

  2. Turn the foot in then turn the foot out (keeping the knee still).

  3. Circle the ankle in both directions.

  4. It is important to start walking on the ankle as soon as possible and so crutches are best avoided. However, if you cannot walk on the ankle, you may need crutches for a short period.

  5. A supporting bandage is not medically necessary but may make some patients feel more comfortable.

  6. Severe sprains may benefit from physiotherapy

Should I take painkillers?

Paracetamol is useful to ease pain. It is best to take it regularly for a few days or so, rather than every now and then. An adult dose is two 500 mg tablets, four times a day. A doctor may prescribe additional painkillers such as codeine if the pain is more severe.  If you are prescribed a combination of paracetamol and codeine (e.g. cocodamol or codydramol) then it is important not to take additional paracetamol as you will accidentally overdose.

Anti-inflammatory medication can be used with paracetamol or as an alternative. There are many types and brands. They relieve pain and reduce inflammation and swelling (often the cause of the pain). You can buy ibuprofen at pharmacies or supermarkets without a prescription. The dose varies depending on your age and other medical problems. Side-effects sometimes occur with anti-inflammatory painkillers. Ask your doctor or pharmacist for advice regarding them

If pain is not controlled by these simple painkillers, do not exceed the recommended dose but see your general practitioner to discuss the possibility of stronger painkillers.

What do I do if my symptoms are not improving?

Sprains of the ankle/foot normally take at least a few days to start improving. They may take weeks to heal properly.
