A sprain is an injury to a ligament that supports a joint, such as the knee or ankle €“ sometimes known as twisting a knee or ankle. A strain is an injury to a muscle or tendon €“ sometimes referred to as 'pulling a muscle'. Symptoms can include:

• Pain around the affected joint or muscle
• Swelling and inflammation
• Inability to put weight on the joint or use it
• Bruising (sometimes at a later stage).

Most strains and sprains happen while playing sports. However, they can occur if a person falls awkwardly, bumps into an object or just over-reaches. Immediate first aid treatment of strains and sprains is to follow PRICE:

• Protect the injured area from further damage by using a support
• Rest and avoid activity for at least 48-72 hours after the injury
• Ice should be applied as soon as possible for at least 30 minutes to help limit swelling
• Compression should be applied by using an appropriate bandage
• Elevation of the area will help to limit the swelling.
