A sprain is a severe tug or twist of the ligaments, which leads to pain and swelling in joints. These sorts of injuries typically occur in the ankle or wrist.

A strain occurs when you severely stretch muscles or tendons.

What are the symptoms?

• Pain or tenderness
• Swelling
• Bruising
• Loss of ability to use the limb
• Muscle spasms

If the injured area looks deformed, or you have difficulty putting weight on it or moving it, this could be a sign of a fracture.

If in doubt, you should seek medical assistance.
