An ankle sprain or strain involves damage to the ligaments (sprain) or muscles and tendons (strain) that support and stabilise the ankle joint. These injuries commonly occur during sports, exercise, or everyday activities when the foot twists or rolls unexpectedly. With the right diagnosis, rehabilitation, and activity modification, most people can reduce pain, restore ankle stability, and safely return to normal activities .Below is a clear guide to what an ankle sprain or strain is, how it happens, what to watch for, how it’s diagnosed, and treatment options available (adapted from information provided by Sports-Health).
Why the Ankle Matters
The ankle plays several key roles:
• Stability: supporting body weight during standing, walking, and running
• Movement: allowing foot motion in multiple directions
• Shock absorption: helping distribute forces through the lower body
• Balance and coordination: providing proprioceptive feedback for movement control. When ankle structures are injured, these functions are disrupted, leading to pain, swelling, weakness, and instability.
How Ankle Sprains and Strains Happen
There are several ways these injuries can develop:
Sudden Twisting or Rolling Movements
- Common during sports or stepping on uneven surfaces, especially when the foot rolls inward (inversion injury).
Overuse or Repetitive Stress
- Repeated loading without adequate recovery can irritate muscles and tendons around the ankle.
Direct Trauma
- Falls, collisions, or awkward landings can damage ligaments or soft tissues.
Previous Injury
- A prior sprain increases the likelihood of reinjury due to reduced stability and proprioception.
Poor Footwear or Mechanics
- Unsupportive shoes or biomechanical imbalances can increase ankle stress.
Recognising the Risk Factors
Factors that increase the likelihood include:
• Participation in running or jumping sports
• Uneven terrain or surfaces
• Previous ankle injuries
• Poor balance or proprioception
• Weak lower-leg muscles
• Inadequate warm-up
• Fatigue
• Improper footwear
How Ankle Sprains and Strains May Present (Symptoms)
Symptoms can vary depending on severity, but commonly include:
• Pain around the ankle
• Swelling and inflammation
• Bruising or discoloration
• Difficulty bearing weight
• Reduced range of motion
• Tenderness to touch
• A feeling of instability or “giving way”
• Stiffness, especially after rest
Diagnosing an Ankle Sprain or Strain
Diagnosis typically includes:
History and Physical Examination
Your clinician will assess symptoms, swelling, joint stability, movement, and weight-bearing ability.
Imaging
• X-rays to rule out fractures or bone injuries
• MRI or ultrasound if significant ligament or tendon damage is suspected
Treatment Options
Non-Surgical (Conservative) Treatment
Most ankle injuries improve with:
• Relative rest and activity modification
• Ice and swelling management
• Compression or bracing/taping
• Physiotherapy focusing on strength, balance, and mobility
• Manual therapy to restore joint movement
• Gradual return to activity and sport
• Pain management strategies when needed. Early rehabilitation is important to prevent long-term instability.
Surgical Treatment
If symptoms persist or instability is severe:
• Ligament repair or reconstruction
• Removal of damaged tissue
• Correction of structural problems. Rehabilitation is essential after surgery to restore function and prevent recurrence.
Protecting Your Ankle Long Term
To reduce injury risk:
• Strengthen ankle and lower-leg muscles
• Improve balance and proprioception
• Wear supportive footwear
• Warm up before activity
• Progress training loads gradually
• Address injuries early before they worsen
• Consider taping or bracing during high-risk activities
When to Seek Professional Help
If you have persistent ankle pain, significant swelling, difficulty walking, or repeated ankle instability, early assessment can help prevent chronic problems and speed recovery.
