Ankle Tendonitis: Symptoms, Recovery and Treatment in the UK

Ankle tendonitis, often referred to as tendinopathy, is a common musculoskeletal condition where one or more of the tendons connecting your lower leg muscles to the bones in your foot become inflamed or irritated. Tendons are the tough, fibrous cords that facilitate movement; when they are subjected to repetitive strain or sudden injury, they can develop small tears.

In the UK, this is frequently seen in runners, athletes, or individuals who have recently increased their activity levels. While the Achilles tendon is the most famous, ankle tendonitis often affects the peroneal tendons (on the outside of the ankle) or the posterior tibial tendon (on the inside of the ankle). Proper identification is key to ensuring the correct rehabilitation path and avoiding long-term mobility issues.

Recognising the Signs

The symptoms of ankle tendonitis typically develop gradually rather than appearing suddenly like a sprain. According to NHS guidance, common indicators include:

• Pain: A dull ache or sharp pain that is most noticeable when starting an activity or after a long period of rest.
• Swelling: Localised puffiness around the affected tendon.
• Stiffness: Difficulty moving the ankle joint, particularly in the morning.
• Warmth and Redness: The area may feel slightly warmer to the touch if acute inflammation is present.
• Crepitus: A grating or 'crunching' sensation when moving the ankle.

The location of the pain helps identify which tendon is involved. Pain on the outer edge of the ankle usually suggests peroneal tendonitis, whereas pain along the inner arch and ankle bone often points towards the posterior tibial tendon.

Tendonitis is primarily an overuse injury. In the United Kingdom, common triggers include the 'too much, too soon' approach to exercise—specifically increasing walking or running mileage without adequate conditioning. Other risk factors include:

• Foot Anatomy: Having very high arches or flat feet (fallen arches) can put abnormal stress on specific tendons.
• Poor Footwear: Wearing worn-out trainers or shoes that do not provide adequate arch support.
• Surface Changes: Shifting from treadmill running to uneven pavement or hills.
• Age and Health: Tendons become less flexible with age. Conditions such as rheumatoid arthritis or diabetes may also increase the risk of tendon issues.

The primary goal of treatment is to reduce inflammation and allow the tendon to heal. NICE (National Institute for Health and Care Excellence) guidelines generally recommend a conservative approach for the first few weeks.

Self-Care: The RICE Protocol

• Rest: Avoid activities that aggravate the pain. You don't need to stay completely sedentary, but high-impact sports should be paused.
• Ice: Apply an ice pack wrapped in a towel for 15–20 minutes several times a day to reduce swelling.
• Compression: Using an elasticated bandage can help support the joint.
• Elevation: Keep your ankle raised above the level of your heart when sitting.

Pain Relief

Over-the-counter medications such as paracetamol or non-steroidal anti-inflammatory drugs (NSAIDs) like ibuprofen can help manage pain. Always consult a pharmacist or doctor before starting new medication to ensure it is suitable for you.

Physiotherapy

If symptoms persist beyond 2-3 weeks, physiotherapy is often the most effective route. A specialist can provide a tailored exercise programme focusing on 'eccentric loading'—exercises that strengthen the tendon while it is lengthening—which is proven to stimulate healing in chronic cases.

If you are struggling with persistent ankle pain that is not improving with rest, speaking to a GP online is a convenient way to get a professional assessment. An online doctor can discuss your symptoms, review your activity history, and provide guidance on the next steps.

A GP can assist by:

• Providing a formal diagnosis based on your clinical history.
• Issuing private prescriptions for stronger anti-inflammatories if required.
• Writing a referral letter for private physiotherapy or an orthopaedic specialist.
• Issuing a sick note (Fit Note) if your job involves heavy lifting or standing and requires a period of recovery.
• Advising on whether an X-ray or MRI might be necessary to rule out stress fractures or significant tears.

Once an ankle tendon has been injured, it is more susceptible to future issues. To prevent recurrence, consider these British Podiatry recommended steps:

Gradual Progression

Follow the '10% rule'—never increase your exercise intensity, duration, or distance by more than 10% per week.

Strength and Conditioning

Incorporate calf raises and balance exercises (such as standing on one leg) into your weekly routine to improve the stability of the ankle complex.

Orthotics

If flat feet are a contributing factor, a GP or podiatrist may recommend insoles to help redistribute pressure away from the posterior tibial tendon.
