What is Achilles Pain?
Achilles pain refers to discomfort felt along the back of the heel or lower calf where the Achilles tendon runs. The Achilles tendon is the strong band of tissue that connects your calf muscles to your heel bone and helps you walk, run, jump, and climb stairs.
Achilles pain often develops gradually due to overuse, tight muscles, or changes in activity, but it can also occur suddenly with a more serious injury such as a tear or rupture.
Early assessment and treatment are important to prevent the problem from becoming chronic and to reduce the risk of more serious tendon damage.
Symptoms of Achilles Pain
Achilles problems can present in different ways depending on the cause. Common symptoms include:
- Aching or stiffness at the back of the heel or lower calf, especially in the morning
- Pain during or after activity such as walking, running, or climbing stairs
- Swelling or thickening along the tendon
- Tenderness to touch a few centimetres above the heel or at the tendon insertion
- Warmth or creaking sensation (crepitus) when the tendon is moved
- Reduced calf strength or difficulty pushing off the foot
- Sudden sharp pain or “popping” sensation in more severe injuries
Struggling With Ongoing Achilles Pain?
Our podiatrists can assess the cause of your Achilles pain and develop a tailored treatment plan to relieve symptoms, restore strength, and reduce the risk of further injury.
Common Causes of Achilles Pain
1. Achilles Tendinopathy (Overuse Injury)
Achilles tendinopathy occurs when the tendon is repeatedly overloaded, leading to irritation, micro-tears, and thickening of the tendon. It often affects runners and people who have increased their activity suddenly.
2. Insertional Achilles Tendinopathy
This type of Achilles pain occurs where the tendon attaches to the back of the heel bone. It may be associated with bony spurs, tight calf muscles, and pressure from shoes.
3. Sudden Increase in Training or Activity
Rapidly increasing running distance, speed, or hill work can overload the tendon before it has time to adapt, leading to pain and stiffness. If this is happening alongside other running-related injuries, see our guide to shin splints.
4. Tight Calf Muscles
Limited flexibility in the calf muscles and Achilles tendon increases tension across the back of the heel with each step, contributing to pain and reduced function.
5. Foot and Leg Alignment Issues
Flat feet, high arches, or poor biomechanics can change the way forces pass through the leg and ankle, placing extra strain on the Achilles tendon. A detailed gait analysis can help identify the contributing factors.
6. Unsupportive or Worn-Out Footwear
Shoes that lack cushioning or support, or that are excessively worn, fail to absorb shock and can increase stress on the tendon during walking and running.
7. Achilles Tear or Rupture
A more serious injury can occur when the Achilles tendon partially or completely tears, often with a sudden sharp pain, a popping sensation, and difficulty pushing off the foot.
When to Seek Immediate Medical Attention
Seek urgent medical care if you feel a sudden “snap” or “pop” at the back of your leg, cannot push off your foot, have severe pain or swelling, or cannot bear weight. People with diabetes or poor circulation should treat any new Achilles or heel pain as a priority.
How is Achilles Pain Diagnosed?
A thorough assessment is important to identify the cause and severity of Achilles pain. Your podiatrist may use:
- Medical history: Discussion of your symptoms, activity levels, footwear, and any recent changes in training.
- Physical examination: Palpation of the tendon, assessment of swelling, thickening, and tenderness.
- Range of motion and strength tests: Checking calf flexibility and muscle strength.
- Gait and biomechanical analysis: Observing how you stand, walk, and run to identify contributing factors. Our sports biomechanics services can also help pinpoint movement patterns linked to tendon overload.
- Imaging tests: Ultrasound or MRI may be used to assess tendon structure and rule out significant tears.
Get a Clear Diagnosis for Your Achilles Pain
Our podiatrists use detailed clinical assessment and imaging where needed to identify the exact cause of your Achilles pain and guide you through a safe, effective recovery plan.
Treatment Options for Achilles Pain
Treatment depends on the underlying cause, how long symptoms have been present, and your activity goals. Many cases improve with structured, non-surgical care.
Conservative Treatments
- Activity modification: Reducing or changing activities that aggravate pain, especially running and jumping.
- Ice therapy: Applying ice packs after activity to help reduce pain and swelling.
- Supportive footwear: Wearing shoes with good cushioning and heel support.
- Heel lifts: Temporary use of small heel raises to reduce tension on the tendon.
- Stretching exercises: Gentle calf and Achilles stretches to improve flexibility.
- Strengthening exercises: Eccentric and progressive loading programs to restore tendon strength.
- Custom orthotics: Prescription insoles to address foot posture and reduce strain on the tendon. Learn more about orthotics.
- Pain relief: Short-term use of medication or topical treatments as advised by your healthcare provider.
Advanced Treatments
- Shockwave therapy: A non-invasive option that may be used for persistent Achilles tendinopathy. Learn more about shockwave therapy.
- Guided injections: In selected cases, injections around the tendon or associated bursae may be considered.
- Immobilisation or boot use: For more severe injuries or partial tears that need reduced load.
- Surgery: Reserved for significant tears or chronic cases that do not improve with comprehensive conservative care.
Preventing Achilles Pain
You can help reduce your risk of Achilles pain by:
- Gradually increasing training volume and intensity instead of making sudden changes.
- Warming up before exercise and cooling down afterwards.
- Including regular calf and Achilles stretches in your routine.
- Strengthening the calves, ankles, and feet to improve support and control.
- Wearing supportive, well-fitting footwear suitable for your activity.
- Replacing worn-out running or sports shoes regularly.
- Addressing early heel pain or tendon discomfort promptly rather than training through pain.
When to See a Podiatrist
Arrange an appointment with a podiatrist if you experience:
- Achilles pain that lasts more than a few days or keeps returning.
- Morning stiffness or pain that is slow to improve.
- Swelling, thickening, or a lump along the tendon.
- Difficulty walking, running, or climbing stairs due to pain.
- A sudden sharp pain or “pop” at the back of the leg.
- Achilles pain in the context of diabetes, inflammatory conditions, or previous tendon injury.
Frequently Asked Questions
Recovery time depends on how severe and how long the problem has been present. Mild, early-stage cases may improve within a few weeks, while more chronic tendinopathy can take several months of structured rehabilitation.
Continuing to run through significant Achilles pain can worsen the problem. In many cases activity needs to be modified or temporarily reduced while a strengthening and rehab plan is put in place. A podiatrist can advise what is safe for your situation.
Not always. Many cases can be diagnosed clinically. Imaging such as ultrasound or MRI is more likely to be recommended if a tear is suspected, symptoms are severe, or there is poor progress with treatment.
Chronic Achilles tendinopathy can cause long-term pain and reduced function if not managed properly. Early assessment, load management, and targeted strengthening greatly reduce the risk of ongoing issues.
