Sprained Ankle Symptoms: What Are They?

Sprained Ankle SymptomsAlthough ankle sprains are much more common than breaks of the ankle, sprained ankle symptoms are often confused with those of an ankle fracture.  As you may recall from an earlier post, ankle sprains are extremely common. In fact, they are perhaps the most common bone and muscle injury of all.  They can occur from nearly any activity but frequently develop during athletics.

Sprained Ankle Symptoms

Lateral Ankle Sprain Mechanism

The most common type (lateral sprain) occurs when the foot turns over (inversion) so that the back of the foot is turned toward the ground. Other types include the medial or deltoid ligament sprain that occurs when the foot twists in the opposite direction (eversion) and the high ankle sprain which occurs with outside rotation (external rotation) of the foot.

Since sprained ankle symptoms are so common and so often confused, let’s take a look at the frequent symptoms for the most common ankle sprain, the lateral ankle sprain.

Sprained Ankle Symptoms

Initial Symptoms

  • Sudden ankle injury
  • Often palpable or audible “pop”
  • Immediate pain on outside of ankle
  • Difficulty walking

Later Symptoms

Sprained Ankle Symptoms

Ankle Sprain

  • Ankle swelling
  • Black and blue on outside ankle (+/- inside ankle and/or foot)
  • Stiffness
  • Painful ambulation

The symptoms of a sprained ankle usually progressively resolve between 2-6 weeks after the injury.  The delayed sprained ankle symptoms differ from the earlier symptoms and slowly improve over time as well.

Delayed Symptoms

  • Resolving swelling
  • Resolving black and blue skin (first purple, then green and then yellow)
  • Lessening pain
  • Reduced stiffness
  • Weakness
  • Instability (sense of ankle giving way)

Most sprained ankle symptoms typically resolve with time.  The weakness, instability and some pain from fatigue or recurrent minor or more significant injuries can persist or recur.  Physical therapy can help prevent this or reduce the recurrence frequency.

The common sprained ankle symptoms often are confused with those following a break of the ankle bones.  It can often be difficult to distinguish between the two without a professional exam and a X-ray.  If you have injured your ankle and you have some of the above symptoms, it is probably a good idea to have your ankle assessed by your Orthopaedic sports medicine doc.
