Twisted Your Ankle? Walking, Ligament Damage & Recovery
When to get checked after an ankle injury, how scans may help and how to return to walking and sport safely.
Is it alright to walk on a sprained ankle?
It depends on the injury and how well you can bear weight. Do not try to walk off severe pain or continue playing sport after a significant twist.
If you cannot put weight on the ankle or manage more than a few steps, seek urgent advice. A fracture or another significant injury needs to be considered before assuming it is a simple sprain.
Once a straightforward sprain has been assessed, gentle movement and gradually increasing weight-bearing as comfort allows are often part of recovery. Follow any specific restrictions given by your clinician.

When should you seek urgent help?
Contact NHS 111 or an urgent treatment service for severe or worsening pain, substantial or increasing swelling, inability to bear weight, or a snap or pop with loss of function.
Being able to walk does not completely rule out a fracture. Let a clinician assess concerning symptoms.
How do ankle sprains happen?
A sprain is an injury to a ligament, the tissue connecting bones and supporting a joint. A strain affects muscle or tendon; tendons connect muscles to bones.
Rolling or twisting beyond the normal range can stretch or tear ankle ligaments. The outer ankle ligaments are commonly involved, but other structures may be injured depending on how the foot moved.
Uneven ground, an awkward landing or a fall can cause an injury during sport or everyday activity.

What symptoms are common?
- Pain around the ankle.
- Swelling and bruising.
- Restricted or uncomfortable movement.
- Difficulty walking or bearing weight.
- A sense of giving way or instability.
These symptoms overlap with fractures and tendon injuries. Swelling or a popping sensation alone cannot tell you which structure is damaged or how severe the injury is.
How is an ankle sprain assessed?
Your podiatrist, physiotherapist or other assessing clinician considers the mechanism, pain location, tenderness, movement and ability to bear weight. They check whether further investigation or urgent referral is needed.
Mild or Grade I sprain
Smaller amounts of ligament damage, often with less loss of function.
Partial or Grade II tear
Partial ligament tearing, with variable swelling, pain and looseness.
Complete or Grade III tear
A complete ligament rupture that may be associated with significant instability. Management depends on the overall injury.
Grades are a useful overview, but the number alone does not determine a return-to-sport date.
Do you need an X-ray, ultrasound or MRI?
X-ray: when a fracture is suspected
Clinical decision tools such as the Ottawa Ankle Rules help trained clinicians decide whether an X-ray is indicated. They consider particular areas of bone tenderness and the ability to bear weight. They are not a substitute for assessment or a home test.
Ultrasound: selected soft-tissue questions
Ultrasound can help assess accessible ligaments and tendons and observe some structures during movement. It does not replace an X-ray when a fracture is suspected and is not necessary for every sprain.
MRI: when further information is needed
MRI may be appropriate for certain deeper or complex injuries or persistent unexplained symptoms. Ultrasound is not automatically superior to MRI; the choice depends on the clinical question.

What helps in the early stages?
Protect the injury and pause aggravating activities. Rest initially while allowing gentle movement when comfortable. A wrapped cold pack can help symptoms; never apply ice directly to the skin. Elevation may help swelling.
Ask a pharmacist or clinician about suitable pain relief. Bracing, taping, crutches or a boot may be advised for an individual injury; not every sprain needs them.
Avoid massage and heat in the first couple of days. Once a significant injury has been excluded, build walking back up gradually rather than forcing a painful limp or staying completely inactive for prolonged periods.
What does rehabilitation involve?
A tailored programme may progress through:
- Movement: restore comfortable ankle mobility.
- Walking: gradually regain a comfortable gait.
- Strength: rebuild calf and ankle capacity.
- Balance: practise control and stability.
- Sport: reintroduce running, jumping and changes of direction as appropriate.
Hands-on treatment or support may be used where helpful, but should sit alongside rehabilitation. A repeat scan is only needed if it would answer a useful clinical question or change management.

How long does recovery take?
Milder sprains may improve over a few weeks; more significant injuries can take substantially longer. Swelling may persist after walking becomes easier.
Return to sport should consider strength, balance, movement and the demands of the activity—not simply how many weeks have passed. Persistent pain, repeated giving way or failure to improve warrants review.
