A broken ankle typically causes severe pain, significant swelling, bruising, visible deformity, and an inability to bear weight. A sprained ankle usually presents with milder symptoms, such as moderate swelling, tenderness, and limited but possible weight-bearing. Key differences include the intensity of pain, presence of deformity, and how quickly symptoms worsen after injury.

Because broken and sprained ankles can look similar at first glance—but require very different treatments—it's important to identify your symptoms accurately and early. Delaying care for a fracture can lead to long-term complications, while unnecessary ER visits for a mild sprain can waste time and money. A free, instant, online symptom check can help you quickly assess your injury, understand possible causes, and decide whether to rest at home, see a doctor, or seek urgent care—giving you clarity in minutes.

Explanation

When trying to tell the difference between a broken ankle and a sprained ankle, there are some key symptoms to look for. A broken ankle usually causes more intense pain and swelling. You might not be able to put any weight on it at all. Sometimes, the ankle might look deformed or have a bruise.

On the other hand, a sprained ankle might still hurt, but the pain and swelling are often less severe. You might still be able to walk, but it could hurt a lot.

Here are some signs to look for:

  1. Pain: A broken ankle usually has more severe pain.
  2. Swelling: Both injuries can cause swelling, but it's often more pronounced in a fracture.
  3. Ability to Walk: Walking or putting weight on a broken ankle is often very difficult.
  4. Appearance: A fracture might cause the ankle to look misshapen.

If you have an ankle injury, you can use a free symptom checker to help assess your symptoms before seeing a doctor. They can do tests to see if it's broken or sprained.
