Ankle Sprains

What is an ankle sprain?

An ankle sprain happens when one or more ligaments are stretched or torn. Sprains often occur when the ankle rolls during sports, a fall, or a step on an uneven surface. A fracture or tendon injury can feel similar, so the right diagnosis matters.

Common symptoms

• Pain or tenderness around the ankle
• Swelling or bruising
• Difficulty walking or putting weight on the foot
• Stiffness or a feeling that the ankle may give way

The amount of swelling does not always show how serious the injury is. Some significant injuries cause less bruising than expected.

Why it happens

A sudden twist is the most common cause. Prior sprains, weak ankle muscles, poor balance, uneven ground, and shoes that do not match the activity can increase the risk.

How we evaluate an ankle sprain

We examine the ankle and foot, review how the injury happened, and test stability. Digital X-rays may be used to look for a fracture. More advanced imaging may be considered when pain continues or a tendon, cartilage, or high ankle injury is suspected.

Treatment options

Treatment is based on the injured ligament and the degree of instability. It may include:

• Protection with a brace, boot, or cast
• Ice, elevation, and short term activity limits
• Guided range of motion and strengthening
• Balance training to reduce repeat sprains
• Physical therapy or custom support when needed
• Surgery for selected unstable or complex injuries

Rehabilitation is an important part of care. Pain may improve before strength and balance fully return.

When to schedule an appointment

Arrange prompt care if you cannot take several steps, the ankle looks out of place, pain is severe, or the foot feels numb or cold. An ankle that keeps giving way should also be evaluated.

Frequently asked questions

How do I know if it is broken?

A fracture and a sprain can cause the same pain, swelling, and bruising. An examination and X-ray are often the best way to tell.

Do I need a boot?

Not every sprain needs a boot. The choice depends on stability, pain, and the location of the injury.

When can I return to sports?

Return is safest when motion, strength, balance, and sport specific movement have recovered, not simply when swelling is gone.

How to prepare for your appointment

Bring your usual walking or athletic shoes and any prior imaging. Note where the pain begins, which activities affect it, whether an injury occurred, and what treatments you have already tried.
