Outer Ankle Pain When Walking? Here's What It Means and What to Do
Updated July 20261 minute read
Pain on the outer side of the ankle when walking is often peroneal tendinopathy (the tendons behind the outer ankle bone) or lingering irritation after a sprain, sometimes with underlying instability. It's usually an overload issue, not an emergency. Load management, ankle strengthening, and balance work typically help. Inability to bear weight with bony tenderness after an injury needs an X-ray.
What this usually means
Most likely causes. Peroneal tendinopathy and lingering effects of a prior ankle sprain (including instability) are common causes of outer-ankle pain with walking. Less common causes. A bony issue or, after injury, a fracture can cause outer-ankle pain — bony tenderness and inability to bear weight are clues.
What you can try at home
Reduce walking on uneven ground temporarily, choose supportive footwear, and keep the ankle gently active. Strengthening the ankle and improving balance addresses the underlying cause, especially if you've sprained it before.
When to see a physical therapist
If outer-ankle pain persists or you also feel unstable, a PT can identify the cause and build a strengthening and balance plan.
Red flags — don't wait
Get urgent care / an X-ray for inability to bear weight with bony tenderness after an injury, a deformed ankle, or a hot feverish joint.
How a PT treats this
Treatment offloads the tendons, strengthens the ankle, and rebuilds balance to address instability.
