A sprained ankle can make every step painful, causing swelling and bruising and making it difficult to walk. With proper treatment and rehabilitation, most people regain strength, balance and confidence in their ankle movement. 

What Is a Sprained Ankle? 

A sprained ankle happens when the ligaments that support the joint are stretched or torn, usually after the foot rolls or twists unexpectedly. This can cause pain, swelling, bruising and difficulty bearing weight. The most common type is an inversion sprain, when the foot rolls inward and the outer ligaments are injured. 

Doctors classify ankle sprains by severity: 
 

  • Grade 1 (mild): Slight stretching of ligaments with minimal swelling or instability
  • Grade 2 (moderate): Partial ligament tear causing more swelling, bruising and limited movement
  • Grade 3 (severe): Complete ligament tear leading to significant pain, instability and difficulty walking 

Sprains often happen during sports, exercise or walking on uneven ground. Risk factors include poor balance, weak ankle muscles or a history of previous sprains, which can make the joint less stable. Even simple activities, such as missing a step or landing awkwardly, can lead to a sprain if the ligaments are overstressed.

 

What Are the Symptoms of a Sprained Ankle? 

Sprained ankle symptoms can range from mild discomfort to severe pain and instability, depending on the extent of ligament damage. Pain typically appears immediately after the injury and may worsen when standing or walking. Symptoms may include: 
 

  • Pain or tenderness around the ankle joint
  • Swelling and bruising, often within hours of injury
  • Difficulty bearing weight or walking
  • Stiffness and reduced range of motion
  • A popping sound or sensation at the time of injury
  • Instability or the feeling that the ankle may give out

How Is a Sprained Ankle Diagnosed?

Your doctor will ask about your injury, check for swelling, bruising, and tenderness, and gently move your ankle to test motion and stability. They may assess strength and balance, and use imaging like X-rays or MRI to rule out fractures or ligament tears and confirm the sprain's grade.

Avoiding weight-bearing and strenuous activity gives the injured ligaments time to heal. Using crutches or a walking boot may help reduce strain on the ankle during the recovery process.
