What is an Ankle Sprain?
An ankle sprain occurs when one or more ligaments in the ankle are stretched or torn. This typically happens when the ankle twists, rolls, or turns beyond its normal range of motion. Sprains are one of the most common lower limb injuries and can range from mild overstretching to complete ligament tears.
The most common type is an inversion sprain, where the foot rolls inward, injuring the ligaments on the outside of the ankle. Without proper treatment, ankle sprains can lead to long-term instability and recurring injuries.
Symptoms of an Ankle Sprain
Symptoms vary depending on the severity of the ligament damage. Common signs include:
- Sharp or aching ankle pain, especially when weight-bearing
- Swelling around the ankle joint
- Bruising or discolouration that may appear within hours
- Tenderness when touching the injured ligaments
- Instability or a feeling that the ankle may “give way”
- Reduced movement or stiffness
- Popping sensation at the time of injury (in some cases)
Injured Your Ankle?
Proper assessment and early treatment are key to preventing long-term ankle instability. Our podiatrists can diagnose your sprain and guide a safe, effective recovery plan.
Common Causes of Ankle Sprains
1. Sudden Twisting or Rolling of the Ankle
A quick change in direction, uneven surfaces, or landing awkwardly can force the ankle out of position, overstretching the supporting ligaments.
2. Sports and High-Impact Activities
Running, basketball, football, tennis, and dancing involve rapid movements that significantly increase the risk of sprains.
3. Weak or Fatigued Muscles
Poor muscle conditioning reduces joint stability, making sprains more likely during high-impact or repetitive activities.
4. Previous Ankle Injuries
A past sprain increases the risk of re-injury due to ligament weakness, scar tissue, or poor neuromuscular control.
5. Inappropriate Footwear
Shoes with poor support, worn-out soles, or high heels can make the ankle more vulnerable to rolling or twisting.
When to Seek Immediate Medical Attention
Seek urgent care if you are unable to bear weight, suspect a fracture, notice severe swelling or deformity, feel numbness, or hear a loud pop at the time of injury.
How Are Ankle Sprains Diagnosed?
Your podiatrist may use several methods to confirm the severity of the sprain:
- Medical history: How the injury occurred and symptoms you are experiencing
- Physical examination: Checking ligament tenderness, swelling, and stability
- Range of motion tests: Assessing stiffness and joint mobility
- Gait assessment: Identifying instability or altered walking patterns
- Imaging: X-rays to rule out fractures; ultrasound or MRI for ligament tears
Get an Accurate Diagnosis
A detailed assessment ensures you receive the right treatment from day one, helping you avoid long-term ankle problems.
Treatment Options for Ankle Sprains
Treatment depends on the severity of the sprain, but most improve with non-surgical care. Early intervention helps promote healing and prevent chronic instability.
Conservative Treatments
- RICE protocol: Rest, Ice, Compression, Elevation during the first 48–72 hours
- Activity modification: Avoiding movements that aggravate the injury
- Bracing or taping: Providing stability and protecting the ligaments
- Supportive footwear: Shoes that reduce rolling and improve alignment
- Custom orthotics: To correct foot posture and reduce strain
- Strengthening and balance exercises: Essential for long-term recovery
- Stretching: Improving flexibility of surrounding muscles
- Pain relief medication: Short-term use when needed
Advanced Treatments
- Shockwave therapy: Useful for chronic ligament injuries or scar tissue
- Guided injections: Reducing inflammation in persistent cases
- Immobilisation boots: For moderate to severe sprains requiring reduced movement
- Surgery: Reserved for complete ligament tears or chronic instability not responding to conservative care
Preventing Ankle Sprains
You can reduce your risk of sprains by:
- Wearing supportive footwear with good grip
- Warming up before exercise and cooling down afterwards
- Improving ankle strength with targeted exercises
- Performing balance and stability training
- Replacing worn-out shoes promptly
- Using braces if you have a history of ankle sprains
When to See a Podiatrist
Book an appointment if you experience:
- Ankle pain lasting more than a few days
- Difficulty bearing weight or walking
- Recurrent ankle sprains or instability
- Swelling that doesn’t improve with rest
- A feeling that your ankle “gives way”
- Concerns about returning to sport safely
Frequently Asked Questions
Mild sprains may improve within 2–4 weeks. Moderate to severe sprains may require 6–12 weeks or longer, depending on ligament damage and rehabilitation progress.
If walking causes pain or limping, reduce weight-bearing and seek professional advice. Continuing to walk on a fresh sprain can worsen the injury.
