Achilles tendon pain is one of the most common lower limb complaints we treat at ModPod Podiatry in Sydney. The Achilles tendon — the thick cord connecting your calf muscles to the heel bone — is the largest tendon in the body. It absorbs force with every step and every push-off during walking, running and sport.
Achilles tendinopathy (the clinical term for Achilles tendon pain and degeneration) develops gradually, usually from a change in activity load or a biomechanical problem left unmanaged. It responds well to treatment when caught early. Ignored, it progresses from morning stiffness to a significant injury that disrupts training and daily activity for months. This post explains what Achilles tendon pain feels like, what causes it, and what treatment works.
What Is Achilles Tendinopathy?
Achilles tendinopathy is a degenerative change in the tendon — not straightforward inflammation. Under repeated load, the tendon fibres break down, producing pain, stiffness and reduced ability to absorb force. The condition is sometimes called tendinitis (implying acute inflammation) or tendinosis (implying degenerative change), though tendinopathy is the preferred clinical term because it encompasses both phases.
There are two distinct locations:
- Mid-portion tendinopathy: pain 2–6 cm above the heel bone, in the body of the tendon. This is the most common type, particularly in runners and active individuals.
- Insertional tendinopathy: pain where the tendon attaches to the heel bone. More common in patients over 40 and responds differently to treatment — some exercises that help mid-portion tendinopathy can aggravate the insertional type.
Identifying the location of your pain matters because it changes the management plan. Our podiatrists establish this at the first appointment.
What Does Achilles Tendon Pain Feel Like?
Morning stiffness is the hallmark symptom of Achilles tendinopathy. The tendon is stiff and painful for the first 10–20 steps after getting out of bed, then gradually eases as it warms up. This warm-up pattern is a reliable indicator of tendinopathy rather than a structural injury.
Other common symptoms include:
- A dull ache along the back of the leg, above the heel
- Pain that increases after sustained walking, running or standing
- Tenderness when you press the tendon between your thumb and index finger
- Visible swelling or thickening in the tendon body
- Pain at the start of a run that eases mid-session, then returns in the hours after
If your pain does not ease with gentle movement but instead worsens, or if you felt or heard a sudden snap, see a clinician immediately — this may indicate a tear rather than tendinopathy.
Achilles Tendinopathy vs a Partial Tear
Tendinopathy and a partial tendon tear can produce similar symptoms, which is why clinical examination matters.
A partial tear typically follows a specific incident — a sudden load, a misstep, a change of direction — and produces sharper, more severe pain. The tendon feels weak under load. A complete rupture produces a sudden snap sound and immediate inability to push off the foot. This requires urgent medical attention.
When the diagnosis is uncertain, ultrasound imaging confirms the tendon’s integrity. Our podiatrists refer for diagnostic ultrasound when a structural injury is suspected — it is non-invasive, accurate and available at most imaging centres in Sydney.

What Causes Achilles Tendon Pain?
Achilles tendinopathy develops when tendon load exceeds the tendon’s capacity to recover between sessions. Common triggers include:
- A rapid increase in running distance, frequency or intensity
- Introduction of hill running or speed work too quickly
- Calf muscle tightness or weakness reducing the tendon’s shock absorption capacity
- Overpronation (inward rolling of the foot during the gait cycle), which twists the tendon under load
- Low-cushion or worn-out footwear that increases tendon loading
- Age-related changes to tendon tissue — tendinopathy is more common in patients over 40
- Certain medications, particularly fluoroquinolone antibiotics, which are associated with tendon damage
For runners, training error — specifically doing too much too quickly — is the single most common cause. Our podiatrists who see running injuries assess training load, biomechanics and footwear together rather than treating the tendon in isolation.
Achilles Tendon Pain Treatment in Sydney
The goal of treatment is to reduce pain, restore tendon capacity and prevent recurrence. A combination of approaches works best.
Load Management
The first step is modifying activity to keep load within what the tendon can tolerate. This does not mean complete rest — tendons need mechanical load to heal. Complete rest allows symptoms to settle, but the tendon does not rebuild its capacity, and pain returns when activity resumes. We work with patients to find the right activity level: enough load to stimulate recovery, without aggravating the tendon.
Eccentric Calf Raises
Eccentric loading — lowering the heel slowly and with control from a raised position — is one of the most well-evidenced treatments for mid-portion Achilles tendinopathy. A 12-week programme of eccentric calf raises produces measurable improvement in pain and function in the majority of patients. Correct technique and progression matter. We prescribe this as part of a structured home programme and review progress at follow-up appointments.
Shockwave Therapy
Shockwave therapy delivers high-energy acoustic waves to the tendon, stimulating cellular repair and reducing chronic pain. It is particularly useful for tendinopathy that has persisted for more than three months or has not responded adequately to exercise rehabilitation alone. Most patients require three to six sessions. ModPod Podiatry offers shockwave therapy at our Sydney clinics.
Custom Orthotics
When overpronation or altered foot mechanics are contributing to Achilles load, custom orthotics address the underlying biomechanical cause. A heel raise element within the orthotic also reduces tensile load on the Achilles tendon during the acute phase, providing pain relief while rehabilitation progresses.
Achilles Pain and Sydney’s Running Culture
Sydney has one of the most active running communities in Australia. Events such as the City2Surf, the Sydney Running Festival and the Blackmores Sydney Marathon draw tens of thousands of participants each year, many of whom increase their training load significantly in the months before race day.
Most Achilles injuries we see in runners come down to training error — specifically, escalating volume or intensity faster than the tendon can adapt. Our sports podiatry team assesses the whole picture: training history, running mechanics, footwear and calf muscle function. Treating just the tendon without addressing why it became overloaded leads to recurrence.
Private health insurance Extras cover applies to most podiatry consultations. Medibank, BUPA, HCF and NIB all include podiatry in ancillary cover — typical rebates range from $30 to $55 per consultation depending on policy level. If you have a qualifying chronic condition, ask your GP about a Medicare Chronic Disease Management (CDM) referral for subsidised podiatry visits.
Frequently Asked Questions
Q: What does Achilles tendinopathy morning stiffness feel like?
A: Most people describe the first 10–20 steps after waking as stiff and sore, with the pain easing gradually as the tendon warms up. This warm-up pattern is a consistent feature of tendinopathy. If pain does not ease with movement or is worse during activity than at rest, see a podiatrist — this may indicate a more significant injury.
Q: How long does Achilles tendon pain take to heal?
A: Mid-portion tendinopathy treated with a structured eccentric exercise programme typically improves over 8–12 weeks. Insertional tendinopathy often takes longer. The outcome depends on adherence to rehabilitation, appropriate load management, and whether the underlying biomechanical cause is corrected.
Q: Can I keep running with Achilles tendon pain?
A: In many cases, yes — with modifications to load. Complete rest is rarely the right answer, as it removes the stimulus the tendon needs to adapt and rebuild. We help patients stay active at a level the tendon can tolerate while recovery progresses. A useful guide: if pain after a run settles within 24 hours and is no worse than before, load is manageable.
Q: When should I see a podiatrist for Achilles pain?
A: See a podiatrist if pain has persisted for more than two weeks, is affecting your walking or running pattern, or if you felt a sudden sharp pain or snap in the tendon. Early assessment leads to faster recovery. Waiting until the pain is severe makes treatment longer and outcomes less predictable.
Q: Does shockwave therapy work for Achilles tendinopathy?
A: Yes, particularly for chronic cases — those persisting more than three months — that have not responded fully to exercise rehabilitation. Clinical evidence supports shockwave for both mid-portion and insertional Achilles tendinopathy, and it is now a standard treatment option for persistent tendon pain.
Achilles tendon pain is manageable with the right treatment started early. Our podiatrists at ModPod Podiatry assess and treat Achilles tendinopathy across our Sydney clinics — CBD, Mosman, Dee Why, Rose Bay and North Ryde. Book online to see one of our podiatrists this week.
