What is an ankle sprain

What is an ankle sprain?

Ankle sprain is used to describe an injury to the ligaments (tough bands of tissue) around the ankle that connect the bones of the leg to your foot. A ‘sprain’ refers to a wrench or twisting of ligaments that is violent enough to have caused overstretching or even a tear but not dislocation.


  • Swelling and/or bruising
  • Pain especially when you bear weight on the affected foot
  • Weakness at your ankle
  • Difficulty using your ankle as you normally would
  • Muscle spasm or cramps
  • Popping sensation or sound at the time of injury
  • Tenderness when you touch the ankle

What can cause an ankle sprain?

A sprain occurs when your ankle is forced to move out of its normal position, causing one or more of the ligaments to overstretch, partially tear or tear completely. An ankle sprain is often caused by sudden rolling of the foot, forcing the joint out of its natural position – as a result, it's sometimes referred to as a "rolled ankle". It’s particularly prevalent in trail or cross-country runners who are likely to be stepping on uneven terrain at high speeds for long periods at a time.
