Quick answer. Ankle pain is most commonly caused by a sprain, but tendinitis, gout, osteoarthritis and stress fractures are also frequent. The main red flag is being unable to bear weight or having an obvious deformity after an injury – go to A&E to check for a fracture.
Ankle pain affects almost everyone at some point, whether from a misstep off a kerb, a twist during sport, or wear and tear over the years. A rolled ankle that swells and bruises is usually a sprain, which is the single most common cause and often settles with simple care at home.
But ankle pain has other causes too – inflamed tendons, gout, arthritis and stress fractures can all be to blame, and the pattern of pain helps tell them apart. This guide covers the common causes, the warning signs that mean you should rule out a broken bone, and which doctor to see. (If your main problem is ankle swelling rather than pain, see our separate ankle-swelling guide.)
At a glance
| Likely cause | Typical clues | First steps |
|---|---|---|
| Sprain (ligament injury) | Pain, swelling and bruising after twisting the ankle | Rest, ice, compression, elevation |
| Achilles or other tendinitis | Pain at the back or side, worse with activity | Relative rest, gradual loading, physio |
| Gout | Sudden, very painful, hot, red, swollen joint – often overnight | See a doctor; treat the flare and urate level |
| Osteoarthritis | Gradual ache and stiffness, worse on use, older adults | Pain relief, exercise, sometimes specialist care |
| Stress fracture | Aching that worsens with activity in runners or after a sharp rise in training | Reduce loading, medical review and imaging |
Red flags: when ankle pain needs urgent care
Most ankle pain can be managed at home, but some signs point to a fracture or serious injury. Go to A&E for assessment and an X-ray if, after an injury, you have:
- Inability to bear weight – you cannot take four steps, even with a limp.
- An obvious deformity, with the ankle or foot looking out of shape.
- Bone tenderness over the bony knobs on either side of the ankle or over specific midfoot bones (the basis of the Ottawa ankle rules doctors use to decide on X-rays).
- Numbness, a cold or pale foot, or a wound exposing the joint.
Call 995 for a severe injury with major deformity, heavy bleeding, or if the person cannot be moved safely. Also see a doctor soon if a hot, red, swollen ankle comes on with fever, which can indicate gout or, rarely, joint infection.
Ankle sprains – the most common cause
A sprain happens when the ligaments that stabilise the ankle are overstretched or torn, usually by rolling the foot inward. It causes pain, swelling and often bruising on the outer ankle. Most sprains are mild to moderate and respond well to the RICE approach – rest, ice, compression and elevation – in the first 48 hours, followed by gentle movement and gradual strengthening.
If you cannot put weight on the ankle, the swelling is severe, or it is not improving after a week or two, get it assessed to exclude a fracture or a more serious ligament tear and to guide rehabilitation.
Tendinitis and overuse injuries
Overuse can inflame the tendons around the ankle, particularly the Achilles tendon at the back of the heel. This tends to cause pain and stiffness that is worse when you start activity and after exercise, and is common in runners and those who have ramped up training quickly. Stress fractures – tiny cracks in bone from repetitive loading – cause a similar activity-related ache and also need a relative drop in training plus medical assessment.
These respond best to load management: reduce the aggravating activity, allow recovery, then rebuild gradually, often with guidance from a physiotherapist or sports medicine physician.
Gout and arthritis
Not all ankle pain follows an injury:
- Gout – a sudden attack of severe pain with a hot, red, swollen joint, often starting overnight, is typical of gout, caused by uric acid crystals. It frequently affects the big toe but can hit the ankle. It needs medical treatment for the flare and, often, longer-term management of urate levels.
- Osteoarthritis – gradual wear of the joint causes an ache and stiffness that builds over months to years, worse with use, more common in older adults or after previous injury.
Because a hot, swollen joint can occasionally be an infection rather than gout, sudden severe joint inflammation with fever should be seen promptly.
Self-care and prevention
For everyday ankle pain without red flags, helpful steps include:
- RICE in the first couple of days after an injury.
- Simple pain relief such as paracetamol if needed.
- Supportive, well-fitting footwear.
- A gradual return to walking, running and sport, building strength and balance to reduce re-injury.
If pain keeps returning, the ankle feels unstable or gives way, or there is no improvement after one to two weeks, arrange a review rather than repeatedly pushing through.
Which specialist should you see?
For ankle pain that is severe, persistent, recurring, or where a fracture or significant ligament injury is suspected, an orthopaedic surgeon can assess the bones, ligaments and joint and arrange imaging. You can find one via the best orthopaedic surgeons in Singapore directory. A GP is a sensible first stop for milder or unclear pain.
If your ankle pain is sport- or overuse-related – tendinitis, a stress fracture or a recurring sprain you want to rehabilitate properly – a sports medicine physician focuses on getting you safely back to activity; see the best sports medicine physicians in Singapore. After any injury, if you cannot bear weight or the ankle looks deformed, go to A&E for an X-ray, and call 995 for a severe injury you cannot move safely.
