Ankle Sprain: Symptoms, Grades, and Treatment

What is an ankle sprain?

An ankle sprain is one of the most common injuries. It can happen during sport, while walking, or after a sudden movement that stretches or tears the ankle ligaments to varying degrees. Although some sprains are mild, neglecting treatment may lead to ongoing pain or reduced joint stability.

What are the symptoms of an ankle sprain?

Common symptoms include ankle pain that worsens with movement or walking, swelling around the joint, bruising or changes in skin color, difficulty putting weight on the foot, tenderness over the injured area, and a feeling of ankle instability in some cases.

What are the grades of ankle sprain?

Ankle sprains are usually divided into three grades. Grade 1 involves mild stretching of the ligaments, with mild pain and limited swelling. Grade 2 involves a partial ligament tear, with more noticeable pain, swelling, bruising, and greater difficulty moving. Grade 3 involves a complete ligament tear, with severe pain or a clear loss of stability; standing or walking on the injured foot may be difficult.

How is an ankle sprain diagnosed?

Diagnosis involves a clinical examination to locate the pain and swelling and assess joint stability. The doctor may request an X-ray to rule out a fracture, or further tests for severe or recurring injuries.

How is an ankle sprain treated?

Treatment depends on the severity of the injury. It commonly includes rest and reducing pressure on the foot, ice to reduce swelling, a compression bandage when needed, elevating the foot, prescribed pain relief or anti-inflammatory medication, physiotherapy to improve movement and strengthen muscles, and a splint or other support in selected cases.

When can an ankle sprain be serious?

See a doctor if pain is severe enough to prevent walking, there is marked swelling or bruising, you cannot put weight on the foot, sprains keep recurring, pain persists without improvement over several days, or a fracture or dislocation is suspected.

How can ankle sprains be prevented?

The risk can be reduced by wearing suitable footwear, strengthening the foot and leg muscles, warming up before exercise, taking care on uneven surfaces, and using ankle support when needed during demanding sports.

Summary

Ankle sprains are common, but correct diagnosis and early treatment help recovery and reduce the risk of repeated injury or poor joint stability.
