Treating sprains and strains
Most sprains and strains can be managed at home using over-the-counter painkillers to ease any pain.
If the injury is minor, you can look after yourself by using "PRICE therapy" and "avoiding HARM". These are described below.
PRICE stands for:
- Protection – protect the affected area from further injury by using a support or, in the case of an ankle injury, wearing shoes that enclose and support your feet, such as lace-ups.
- Rest – stop the activity that caused the injury and rest the affected joint or muscle. Avoid activity for the first 48 to 72 hours after injuring yourself. Your GP may recommend you use crutches.
- Ice – for the first 48 to 72 hours after the injury; apply ice wrapped in a damp towel to the injured area for 15 to 20 minutes every two to three hours during the day. Don't leave the ice on while you're asleep, and don't allow the ice to touch your skin directly because it could cause a cold burn.
- Compression – compress or bandage the injured area to limit any swelling and movement that could damage it further. You can use a simple elastic bandage or an elasticated tubular bandage available from a pharmacy. It should be wrapped snuggly around the affected area, but not so tightly that it restricts blood flow. Remove the bandage before you go to sleep.
- Elevation – keep the injured area raised and supported on a pillow to help reduce swelling. If your leg is injured, avoid long periods of time where your leg isn't raised.
For the first 72 hours after a sprain or muscle strain, you should avoid HARM. This means you should avoid:
- Heat – such as hot baths, saunas or heat packs.
- Alcohol – drinking alcohol will increase bleeding and swelling, and slow healing.
- Running – or any other form of exercise that could cause more damage.
- Massage – which may increase bleeding and swelling.
Moving sprained joints
Most healthcare professionals recommend you don't stop using a sprained joint. The injury will heal quicker if you begin to move the joint as soon as you're able to do so without experiencing significant pain.
Your doctor may be able to teach you a number of exercises that will help you improve the joint's functionality.
If you have a severe ankle sprain, you may be advised not to use it for a while, or even have it put into a cast for a week or so.
Immobilising strained muscles
Depending on your injury, the advice for muscle strains can vary. You may be advised to keep your injured muscle still for the first few days. Your doctor may recommend using a brace, cast or splint to help keep it as still as possible.
The aim of immobilising the muscle is to allow it to start healing, so you can move it without tearing or pulling it again in the same place. After a few days, you'll probably be advised to start using the muscle again.
Paracetamol is usually recommended for painful sprains or strains. If it doesn't help, you may need an additional stronger painkiller – such as codeine – that's only available on prescription.
Your GP may also prescribe a non-steroidal anti-inflammatory drug (NSAID) cream or gel, such as ibuprofen or ketoprofen, to help treat pain. Gently apply the cream or gel to the injured area and wash your hands immediately afterwards.
Ketoprofen can make your skin sensitive to light (photophobia). You should avoid exposing treated areas of skin to direct sunlight or artificial sources of light, such as sunlamps or sun beds, during treatment and for two weeks afterwards.
Oral NSAIDs, such as ibuprofen tablets, can also help reduce swelling and inflammation. However, they shouldn't be used in the first 48 hours after the injury because they may delay healing.
For more severe injuries, particularly muscle strains, your doctor may consider referring you for physiotherapy.
Physiotherapy aims to restore movement and function to an injured area of the body. The physiotherapist may show you exercises to help improve the range of motion and return normal function to the injured area.
This may reduce your risk of experiencing long-term problems or injuring the area again.
The length of time it takes to recover from a sprain or strain depends on how severe it is.
Generally, after an ankle sprain you'll probably be able to walk a week or two after the injury. You may be able to use your ankle fully after six to eight weeks, and you'll probably be able to return to sporting activities after eight to 12 weeks.
For muscle strains, the time it can take to recover can vary considerably. Some people recover within a few weeks, whereas others may not be able to return to their normal activities for several months.
Some people may experience continued problems, such as pain, intermittent swelling or instability, for months, or even years, after the original sprain or strain.
Contact your GP if your injury doesn't improve as expected or your symptoms get worse. They may consider referring you to an orthopaedic specialist for further assessment and treatment.
It's rare to need surgery to repair sprains or strains. It's usually only required for severe muscle strains, particularly those in professional sports people.
In these cases, without surgery, it's likely the affected muscle won't fully regain its former strength, and the person's performance may be affected.
For people who aren't sports professionals and those with more minor strains, the loss of muscle strength is usually too mild, or the risk of repeated injuries too low, to justify the risks of surgery.
Surgery is rarely carried out for sprains because it's unclear whether it's any more effective than less invasive treatments.
