Foot & ankle
Ankle sprain
Why an ankle may still feel unsteady after the swelling settles
What it means
A lateral ankle sprain involves ligaments on the outer ankle, often after the foot rolls inward. Some people continue to experience giving way. Persistent instability can involve range of motion, strength, and the ability to control the ankle under changing loads. [1, 2]
What I check in the clinic
If a curb or uneven ground is where you hesitate, I compare stepping down, moving the knee forward over the foot, and how well you can steady yourself. We can change one part of the task and check whether confidence or control improves.
What the evidence says about care
Rehabilitation commonly includes balance and exercise progressions. Return-to-sport consensus considers pain, ankle function, confidence, control, and sport tasks together. Balance training studies support using it for some people with chronic ankle instability. [3, 4, 1]
Common questions
Why is the sidewalk fine but grass still makes my ankle feel shaky?
I’d ask which surface or turn makes you hesitate. With support nearby, we can compare a manageable step or turn and see what helps you feel more in control.
What would I notice on my regular walk if I’m getting steadier?
Notice which curbs or turns still make you slow down, and whether that changes on the same route. Those details can help us plan the next challenge.
The swelling is better. Why do I still hesitate at the curb?
Show me when you hesitate. We can compare a low, supported step with a simpler movement and see what changes when the task feels safer.
What if the ankle feels good in practice but unreliable when I have to react quickly?
Tell me what happened when you had to react. That gives us a different skill to assess before we decide how to build back toward it.
When should I get the injury checked?
Get assessed promptly if you can’t bear weight after the injury or have marked bone tenderness. A clinician can check whether an X-ray is needed. [1]
What should I bring to an evaluation?
Bring one example of a movement or activity you want back, along with any relevant imaging or treatment notes you already have.
