At RAD Clinics, we often see patients who feel worried because their ankle hurts and they are not sure why. Sometimes pain starts after a twist, fall, or sports injury. Other times, it appears gradually or suddenly, with no obvious trigger.
There are many causes of ankle pain. Pain can come from ligaments, tendons, joints, bones, cartilage, nerves, or inflammation around the ankle. This guide explains common causes of ankle pain, including ankle pain without injury, ankle pain and swelling, sudden ankle pain without injury, and pain in specific ankle locations. It is general information only and should not replace advice from your own GP or healthcare professional.
Who is this guide for?
This guide is for adults with ankle pain, swelling, stiffness, soreness, or reduced movement. It may help if you have rolled your ankle, increased activity, changed footwear, noticed a swollen ankle without injury, or developed pain that seems to have started “for no reason”.
Seek urgent medical help if the pain is severe, you cannot put weight on the ankle, the joint looks deformed, the ankle is hot and red, you feel very unwell, or swelling is linked with chest pain or breathlessness.
What are the most common causes of ankle pain?
Ankle pain can arise from several structures. Common causes include:
- Ankle sprains: stretched or torn ligaments, usually after twisting the ankle.
- Tendon problems: irritation in tendons such as the Achilles, peroneal, or posterior tibial tendon.
- Arthritis: joint wear or inflammation causing pain, stiffness, swelling, or reduced movement.
- Gout: crystal-related inflammation that can cause sudden, intense pain and swelling.
- Synovitis or bursitis: inflammation of the joint lining or small cushioning sacs.
- Bone stress or nerve irritation: less obvious causes of ongoing symptoms.
What causes ankle pain without injury?
Not all ankle pain is caused by trauma. Causes of ankle pain without injury can include tendon overuse, osteoarthritis, inflammatory arthritis, gout, synovitis, cartilage irritation, nerve compression, or a bone stress reaction. Symptoms may follow subtle changes such as more walking, long periods of standing, a new exercise routine, or less supportive footwear.
What causes ankle pain and swelling together?
Ankle pain and swelling usually suggest irritation, inflammation, or injury in or around the joint. This may happen with a sprain, tendon inflammation, arthritis, gout, bursitis, synovitis, or fluid build-up. A swollen ankle without injury can still be an MSK problem, but swelling may also relate to circulation, medicines, lymphatic issues, fluid retention, or wider medical conditions.
What causes ankle pain in specific locations?
The location of pain can give useful clues about the affected structure:
- Outside of the ankle: lateral ligament sprain, peroneal tendinopathy, sinus tarsi syndrome, instability, or arthritis on the outer side.
- Inside the ankle: deltoid ligament injury, posterior tibial tendon problems, medial ankle arthritis, or tarsal tunnel syndrome.
- Back of the ankle: Achilles tendinopathy, retrocalcaneal bursitis, Achilles tendon tear, or posterior ankle impingement.
- Front of the ankle: anterior ankle impingement, joint inflammation, osteoarthritis, tendon irritation, or cartilage injury.
What causes ankle pain in women specifically?
Ankle pain in women can have the same causes as ankle pain in men, but some factors are more common. Ligament laxity, hypermobility, footwear-related strain, and pregnancy-related swelling can contribute. Women are also more likely to develop some autoimmune joint conditions, including rheumatoid arthritis, which may cause pain, swelling, stiffness, and flare-ups.
What causes painful, swollen ankles in both legs?
Painful, swollen ankles in both legs often need broader thinking than swelling in one ankle. Possible causes include chronic venous insufficiency, heart-related fluid retention, kidney or liver disease, medication side effects, inflammatory arthritis, reduced mobility, and obesity-related fluid retention. Seek urgent advice if swelling comes with breathlessness, chest pain, severe illness, faintness, or rapid deterioration.
What causes sudden ankle pain without injury?
Sudden ankle pain without injury can happen with gout, an inflammatory arthritis flare, tendon injury, infection, or sudden joint inflammation. Gout is a common cause of sudden, severe ankle pain and swelling, often with warmth, redness, and extreme tenderness. Sudden sharp pain, weakness, fever, spreading redness, or feeling generally unwell should be assessed promptly.
How can a private MSK scan or injection help with ankle pain?
At RAD Clinics, our musculoskeletal ultrasound assessments can help identify many common causes of ankle pain. Ultrasound can assess tendons, ligaments, bursae, joint fluid, synovitis, and soft tissue changes. It can also assess some structures dynamically while the ankle moves.
You do not need a GP referral to book an MSK ultrasound assessment with us for suitable non-urgent musculoskeletal concerns. Patients can self-refer and contact RAD Clinics directly to discuss availability and appointment options.
If an injection is clinically appropriate, ultrasound guidance allows treatment to be placed accurately. Options may include corticosteroid injections, ultrasound-guided joint injections, tendon sheath injections, bursa injections, or other image-guided pain management procedures. Injections are not suitable for every ankle problem, so we focus on understanding the likely cause first.
Fee disclaimer: Any fees mentioned by RAD Clinics are subject to change. Please check our current fee guide or contact the clinic directly before booking, rather than relying on older online information.
Key takeaways
- Ankle pain causes can include ligament injuries, tendon problems, arthritis, gout, nerve irritation, bone stress, and inflammation.
- Ankle pain without injury is common and may be linked to overuse, arthritis, gout, or tendon problems.
- Pain location often helps identify the affected structure.
- Swelling in both ankles may suggest a wider medical cause and should not be ignored.
- A private MSK ultrasound scan at RAD Clinics can help clarify persistent ankle pain and guide treatment decisions.
Conclusion
Ankle pain causes can range from simple sprains and tendon irritation to arthritis, gout, swelling-related problems, or less obvious bone and nerve issues. If your ankle pain is persistent, recurrent, swollen, or affecting how you walk, an MSK assessment can help you understand what may be happening.
At RAD Clinics, we aim to make the process clear and reassuring. Where appropriate, our private MSK ultrasound scans and ultrasound-guided injection services can help support a more accurate diagnosis and a more targeted treatment plan. For personal concerns, please speak to your own GP or healthcare professional.
Common questions about Coccydynia Injection
Can ankle pain be caused by arthritis?
Yes. Osteoarthritis can cause pain, stiffness, and reduced movement. Inflammatory arthritis can cause swelling, warmth, stiffness, and flare-ups.
Is ankle swelling without pain serious?
Sometimes it is mild and temporary, but persistent swelling, swelling in both ankles, or swelling with breathlessness, chest pain, or feeling unwell should be medically assessed.
Can gout affect the ankle?
Yes. Gout can affect the ankle and may cause sudden severe pain, swelling, warmth, redness, and tenderness.
What causes pain on the inside or outside of the ankle?
Outside ankle pain is often linked to sprains, peroneal tendon problems, instability, or arthritis. Inside ankle pain may involve the deltoid ligament, posterior tibial tendon, arthritis, or nerve irritation.
