Quick answer (60 sec read) Achilles tendinopathy is pain and stiffness at the back of the heel or mid-calf, typically worse first thing in the morning or at the start of activity. It's not a tear or an inflammation — it's a tendon-capacity problem. The approach with the strongest evidence isn't rest: it's progressive loading (slow, heavy calf raises) over 6–12 weeks, with manual therapy and (for chronic cases) shockwave therapy as adjuncts. Most patients keep running through rehab at modified volume. AHPRA OST0004003860 · Educational content, not medical advice.
Achilles tendinopathy — assessment and management
Achilles tendinopathy is one of the most common tendon presentations seen in runners, walkers, and recreational athletes. It usually presents as pain and stiffness in the back of the heel or mid-calf region, often worse at the start of activity. The current standard of care centres on progressive loading — adapted to the stage of the tendon and to your activity level. Max sees Achilles tendinopathy regularly across all three Sydney clinics.
What Achilles tendinopathy is
The Achilles is the thick tendon connecting the calf muscles (gastrocnemius and soleus) to the heel bone (calcaneus). Tendinopathy is a clinical term for a tendon that has become painful, stiff, and less able to tolerate the loads it normally would.
Contemporary understanding (the Cook & Purdam continuum) describes tendons as moving through three overlapping stages — reactive, disrepair, and degenerative — depending on how they've been loaded over time. Older terminology like "tendinitis" implied inflammation; current evidence shows the chronic form is largely a problem of tendon structure and load tolerance rather than active inflammation.
Two main subtypes are seen:
- Mid-portion Achilles tendinopathy — pain 2–6 cm above the heel insertion
- Insertional Achilles tendinopathy — pain right at the heel bone, often with thickening or a bony prominence
How it typically presents
- Pain or stiffness at the back of the heel, calf, or both
- Worse first thing in the morning, or after sitting
- Pain at the start of activity that may "warm up" and ease, then return after
- Tenderness when the tendon is squeezed
- Sometimes a visible or palpable thickening of the tendon
- Reduced calf strength compared with the other side
Onset is usually gradual, often after a change in training load — more volume, more intensity, new shoes, hill running, or return after a layoff.
How Max assesses Achilles tendinopathy
An initial assessment includes:
- A detailed history — when the pain started, how it behaves with load, recent training changes, footwear, and previous injuries
- Clinical examination — palpation of the tendon (mid-portion and insertion), single-leg heel raises (load tolerance, calf endurance), single-leg hop where appropriate, ankle dorsiflexion range, and screening of the foot, knee, and hip
- Differential consideration — Achilles paratendinopathy, retrocalcaneal bursitis, posterior ankle impingement, and (rarely but importantly) signs of partial or complete tendon rupture
Most Achilles tendinopathy is a clinical diagnosis — imaging isn't routinely needed. Ultrasound or MRI is considered when the picture is unclear, when there's suspicion of a tear, or when symptoms haven't responded as expected.
How osteopathy may help — the management approach
Management is built around progressive loading. The tendon needs load to adapt — but the right kind, in the right dose, at the right time. A typical staged framework runs:
- Isometric loading — holding the calf in a contracted position. Useful for early-stage symptom management and pain modulation.
- Heavy slow resistance — slow concentric/eccentric calf raises with progressive weight. The workhorse of tendon adaptation.
- Energy-storage loading — hopping, plyometrics, and faster movements. Bridges back to running and sport.
Alongside loading, a treatment plan typically includes:
- Hands-on osteopathy — manual therapy targeting the calf, ankle, and connected regions
- Activity modification (not rest) — staying active in a tolerable way rather than stopping entirely; see running and osteopathy for running-specific load
- Footwear consideration — heel-drop, cushioning, and shoe age
- Shockwave therapy (ESWT) — one option for selected presentations, particularly mid-portion Achilles tendinopathy that hasn't responded to loading alone. Used selectively, not as a default
- Dry needling — used selectively for surrounding muscle restrictions where clinically indicated
- Imaging or onward referral — if features suggest a different diagnosis or a structural concern
What a course of care typically looks like
Tendons are slow to adapt. Most patients see noticeable change in symptoms within 6–12 weeks of consistent loading, with full rehabilitation often running over 3–6 months — particularly for mid-portion presentations. A structured return to sport plan bridges the final stage.
Initial appointments are usually weekly or fortnightly while the loading programme is established and adjusted, tapering as you progress. Many patients continue running through the rehab process at a modified volume and intensity.
When to see your GP or A&E instead
Most Achilles tendinopathy is a non-emergency musculoskeletal presentation. However, see your GP or A&E if:
- You had a sudden severe pain in the back of the calf or heel (often described as a "kick" or "snap"), with difficulty pushing off the foot — this can indicate Achilles tendon rupture
- There is visible deformity, severe swelling, or bruising that's developed quickly
- You have numbness, pins and needles, or weakness in the foot suggesting nerve involvement
- Systemic symptoms (fever, unexplained weight loss, night pain) accompany the heel pain
If you're not sure, contact your GP or attend your nearest emergency department.
Frequently asked
Q. How long does Achilles tendinopathy take to recover? Variable. Most patients see meaningful change within 6–12 weeks of consistent loading, with full return to higher-impact activities often over 3–6 months. Insertional presentations can be slower than mid-portion. Consistency with the loading programme is the single biggest factor.
Q. Should I stop running? Usually not. Complete rest doesn't help the tendon adapt — load (the right kind, at the right dose) does. Most patients can keep running through rehab with modified volume, intensity, and surface. Max will work out what's tolerable with you.
Q. Is "tendinopathy" the same as "tendinitis"? Tendinitis implies an inflammatory process. For chronic Achilles tendon pain, the underlying process is largely structural and load-related rather than actively inflammatory. Tendinopathy is the more accurate term and the one used in current evidence-informed practice.
