Almost everyone, at some point in their lives, has experienced the sharp pain that follows an ankle injury. Ankle sprains are among the most common musculoskeletal injuries. Despite their frequency, they should not be underestimated, as poor management or inadequate treatment can lead to chronic problems.
What is an ankle sprain?
It is an injury to the ligaments, the tough, fibrous bands of connective tissue that connect one bone to another within a joint, providing stability and limiting excessive movement. When the ankle is subjected to a force that takes it beyond its normal range of motion, these ligaments are overstretched and partially or completely torn. Essentially, a sprain is the ligament's response to extreme stress.
PREMIUM QUALITY
Lateral sprain (inversion)
It accounts for about 85% of all sprains. It occurs when the foot rolls inward (inversion), stretching or tearing the ligaments on the outer (lateral) side of the ankle.
Medial sprain (eversion)
It occurs when the foot turns outwards (eversion), injuring the ligaments on the inner (medial) side of the ankle.
Syndesmosis sprain (or “high” ankle sprain)
It injures the ligaments that connect the tibia and fibula just above the ankle, maintaining the stability of the joint. It usually occurs due to a forced external rotation of the foot. It is known for being more painful and having a longer recovery time.
Most common causes
Any movement that forces the ankle beyond its normal limits can cause a sprain. Typical situations include stepping on an uneven surface, improper landings after a jump, twisting during sports, incorrect foot placement while walking, inappropriate footwear, muscle fatigue, or a previously injured ankle.
Symptom
Symptoms vary depending on the severity of the sprain, but generally include pain, especially when putting weight on the foot or touching the ligament area, swelling (edema), bruising (ecchymosis), tenderness to the touch, instability, functional limitation, and stiffness.

Differences between sprain, dislocation and fracture
| Feature | Sprain | Dislocation | Fracture |
|---|---|---|---|
| Affected structure | Ligaments | Articular surfaces of bones | Bones |
| Pain | Located on the sides of the ankle. | Very intense and debilitating. | Punctual, very intense when palpating the fracture point. |
| Visible deformity | Generally not. Swelling can mimic it. | Yes, The joint has an abnormal shape. | There may or may not be one |
| Swelling | Fast and localized. | Immediate and massive. | Variable, it can be very extensive. |
| Mobility | Limited by pain and swelling, but possible. | Impossible. The patient avoids any movement. | Very painful, sometimes a crackling sound (crepitus) is felt. |
| Weight support | Painful, but often possible in mild degrees. | Impossible. | Generally impossible and unbearably painful. |
When to go to the doctor?
It is recommended to seek immediate medical attention if the pain is very intense or does not subside with rest and ice, if you cannot put any weight on the injured foot, if the ankle, foot or leg is visibly deformed, if you heard a popping sound at the time of the injury, if you experience numbness in the foot or toes, if the symptoms do not improve after 2-3 days of self-care, or if it is a recurring injury to the same ankle.
Diagnosis and medical evaluation
Medical history and physical examination
The doctor will ask about the injury and symptoms. They will palpate the ankle to locate the point of maximum pain, assess range of motion, ligament stability, and check circulation and sensation in the foot.
imaging tests
X-ray to rule out a bone fracture, musculoskeletal ultrasound to visualize the condition of ligaments and tendons and detect tears, and Magnetic Resonance Imaging (MRI) for complex cases, severe sprains that do not improve, or when associated injuries are suspected, as it provides detailed images of all soft tissues.
Sprain severity classification
- Grade I (Mild): Mild ligament stretching with micro-tears. Mild pain and tenderness, minimal swelling. Normal stability.
- Grade II (Moderate): Partial ligament tear. Moderate to severe pain, noticeable swelling and bruising. Difficulty bearing weight on the foot. Slight instability.
- Grade III (Severe): Complete ligament rupture. Intense pain, significant swelling and bruising. Inability to bear weight on the foot. Clear joint instability.
Treatment and recommendations
RICE Method
- RRest: Avoid putting weight on the foot. Use crutches if necessary.
- I(Ice): Apply cold compresses for 15-20 minutes, every 2-3 hours.
- CCompression: To use a neuromuscular bandage elastic to reduce swelling.
- EElevation: Keep the ankle elevated above the level of the heart, especially during the first few hours.
Medication and pain management
Pain relievers and non-steroidal anti-inflammatory drugs (NSAIDs) can be used as directed by a doctor or pharmacist to control pain and inflammation.
Physiotherapy and rehabilitation
It is necessary **** for a full recovery and to prevent relapses. A physiotherapist will design a program that usually includes pain and swelling management, exercises to regain range of motion, progressive strengthening of stabilizing muscles and proprioceptive training, and specific exercises to return to sports or daily activities.
Surgery
It is rare and is reserved for complete ruptures with severe instability that do not respond to conservative treatment, chronic and unstable ankle sprains that cause recurrent failures, and associated injuries.
Exercises to recover from an ankle sprain
- While seated, it is recommended to "draw" the letters of the alphabet in the air with your thumb. Move gently.
- Flexion-extension, standing, bring your toes towards your nose and then point them towards the ground.
- Towel stretch: Sitting with your leg extended, pass a towel over the sole of your foot and gently pull it towards you.
- Strengthening with a resistance band: While seated, place a resistance band around your foot and anchor it to a fixed point. Perform eversion and dorsiflexion movements; and proprioception (balance) exercises by standing on one foot (the injured one) on the ground. Then progress to an unstable surface (cushion).
How long does it take for an ankle sprain to heal?
Recovery time according to grade
- Grade I: From 1 to 3 weeks.
- Grade II: From 3 to 6 weeks.
- Grado III: From 6 weeks to 3 months or more.
Factors influencing recovery
The severity of the injury, age and general health, adherence to treatment, history of previous injuries, and the type of sprain.
Can a poorly healed sprain cause problems?
Yes, a sprain that is improperly treated or not fully rehabilitated can cause chronic ankle instability, persistent pain, stiffness and loss of mobility, post-traumatic osteoarthritis, and tarsal sinus syndrome, with chronic pain on the outside of the ankle.
How to prevent ankle sprains
Strengthening and proprioception
Keeping the muscles around the ankle strong and regularly working on balance (standing on one foot) is the best prevention.
suitable footwear
Wear well-fitting shoes with good arch support and non-slip soles. For sports, use footwear specifically designed for that activity and surface.
Attention to the environment and preparation
Be mindful of uneven surfaces when walking or running. Warm up properly before exercising and stretch afterward. Avoid activities on uneven terrain if you are fatigued.
Ankle sprain in specific cases
Ankle sprain in athletes
It requires aggressive management and complete rehabilitation before returning to sport. Emphasis is placed on proprioception and sport-specific exercises. A premature return is a major risk factor for relapse.
Ankle sprain in children
Ligaments in children are usually stronger than the growth plates (physes). Therefore, in the case of a sprain, a growth plate fracture should always be ruled out. Treatment is generally conservative, and recovery is faster than in adults.
Ankle sprain in older adults
Loss of balance, muscle weakness, and potential vision problems increase the risk of falls. A sprain can have a greater impact on mobility and independence. Rehabilitation should be more cautious.
Frequently Asked Questions (FAQs)
How can you tell if it's a grade 1 or 2 sprain?
Grade 1 is painful but allows for relatively normal walking, and swelling is mild. Grade 2 presents with more acute pain upon weight-bearing, noticeable swelling and bruising, and a limp. Only a doctor can confirm this.
What happens if I have a sprain and keep walking?
Walking on a sprained ankle aggravates the injury, increases inflammation and pain, and delays healing. In severe cases, it can turn a partial tear into a complete tear.
What should I not do if I have a sprained ankle?
Do not apply heat for the first 72 hours (it increases inflammation). Do not perform deep massages during the acute phase. Do not take alcohol, nor Do not force movement or try to "see if it holds" by putting all your weight on it.
How can you tell if a sprain is external or internal?
If there is pain/swelling on the outside (below and around the lateral malleolus), it is a lateral sprain. If the pain is on the inside (around the medial malleolus), it is a medial sprain. Lateral sprains are overwhelmingly more common.
How to sleep with a sprained ankle?
Place one or two pillows under the affected foot and leg to keep the ankle elevated above heart level. This helps reduce nighttime swelling and pain. Avoid sleeping on your side with your injured ankle on top of you.
