What Should You Assess When the Achilles Area Hurts After Running?
Pain in the Achilles area after running may involve tendon loading, calf-muscle demand or insertional compression. First locate the pain: the calcaneal insertion, tendon midportion and deeper calf are different assessment regions. Compare that map with running history and a tolerable heel raise; knee position changes calf demand but does not isolate a single painful structure.
I first separate a sudden loss of push-off, which needs an acute-injury pathway, from a gradual load-related complaint. For the latter, knee position helps compare calf findings while the heel symptom remains the reference. I support the ankle and compare tolerable calf muscle-belly contact rather than carrying pressure onto a sensitive Achilles insertion. Reduced calf tenderness and improved tendon-load tolerance must be recorded separately.
This article shows how RSM students assess Achilles pain after running, distinguish tendon-dominant symptoms from soleus or gastrocnemius load sensitivity, palpate by anatomical layer, select an appropriate first treatment focus and re-test the same running, hopping or heel-raise load.

1. Achilles Pain After Running Assessment: Pain Location, Calf Load & Tendon Load
I first ask exactly when the symptom appears: at the start of running, after acceleration, on hills, during repeated jumping, at push-off, after the session, or on the first steps the following morning. Then I map whether pain is in the tendon midportion, directly at the calcaneal insertion, deep and proximal in the soleus region, superficial in gastrocnemius, or more diffuse around the posterior ankle. I also ask whether the pain remains local or spreads toward the calf, heel or medial ankle as the load continues.
The same running complaint can come from different load histories. Recent increases in distance, speed, hill work, court sessions, sprinting, footwear change, recovery loss or a return after rest can all change how the calf–Achilles system is challenged. A runner with midportion stiffness after speed work and a tennis player with deep calf fatigue after repeated acceleration may both point to the Achilles area, but the first-session question is not necessarily the same.
The baseline must be the athlete’s familiar symptom in a meaningful task: pain location, the phase that provokes it and the load required to reproduce it. This gives the clinical assessment a direction before the therapist applies pressure to the painful region.
2. Achilles Tendon or Soleus Pain? Bent-Knee Heel Raise & Clinical Palpation
Achilles-area pain: location and load change the plan
Finding to compare | Next assessment decision |
Pain at the calcaneal insertion | Record dorsiflexion and compression sensitivity; avoid transferring the same contact and range used for midportion symptoms. |
Pain along the tendon or deeper calf during heel raises | Compare straight- and bent-knee loading, pain location and heel-rise control. |
Sudden pop, loss of push-off, marked bruising or a tendon gap | Use an acute-injury referral pathway rather than a calf-massage trial. |
This is an RSM assessment summary of the comparisons explained below, not a set of stand-alone diagnostic tests.
The Achilles tendon transmits force from gastrocnemius and soleus to the calcaneus, but that does not mean all posterior-ankle pain is tendon-dominant. Gastrocnemius crosses the knee and ankle; soleus acts below the knee and is heavily challenged during repeated running and bent-knee plantar-flexion demands. Changing knee position does not isolate one muscle perfectly, but it can change the relative load and help the therapist identify which task reproduces the athlete’s familiar complaint.
Anatomy note: Ultrasound found non-uniform motion within the Achilles tendon; subtendon loading or organization is a proposed explanation, not a proven cause.
I compare a straight-knee heel raise with a bent-knee heel raise, then observe whether the symptom is local to the tendon, deeper in the calf, or changes with repetition and fatigue. The useful finding is not simply that a task feels hard. It is whether the client’s known pain appears at a clear anatomical landmark, where it spreads, and whether heel-rise height, push-off biomechanics or calf control changes at the same time.
Palpation follows the map. First locate the calcaneal insertion and tendon midportion, then distinguish superficial gastrocnemius from deeper soleus by knee position, contact depth and the response to active movement. A tender tendon that does not reproduce the athlete’s recognisable running pain has a different meaning from a tendon that matches the history, heel-rise loading and pain map. Accurate depth and direction are more important than stronger pressure.
3. Achilles Tendon Load Assessment: Ankle Motion, Talus & Running Kinetic Chain
As the runner's tibia advances over the planted foot, the ankle dorsiflexes while the calf–Achilles system controls progression. Later in stance, soleus and gastrocnemius generate plantarflexion as the heel rises. Subtalar motion helps the foot accommodate load; it does not provide a stand-alone explanation for tendon pain.
I compare heel-down tibial progression with a controlled heel raise, observing where the familiar pain begins and whether the heel lifts early. I then compare straight- and bent-knee raises with the same hand support and heel height. This makes the joint motion and calf demand explicit instead of judging a general impression of poor push-off.
If a relevant ankle-motion restriction changes after a tolerable mobilisation within scope, I repeat the same heel-down movement before reassessing the raise. Tendon excursion and calf tissue glide are considered alongside active dorsiflexion and plantarflexion; touch alone does not establish an adhesion or justify claiming that fascia caused the pain.
4. Achilles Pain Assessment: Insertional, Midportion, Bursa & Rupture Red Flags
Midportion symptoms and insertional symptoms should not be treated as the same presentation. Pain located directly where the tendon meets the calcaneus can be more sensitive to compression in dorsiflexion; pain several centimetres proximal to the insertion may behave differently under tendon loading. Retrocalcaneal-bursa irritation, paratenon involvement and nearby bony prominence can also change the symptom map. The treatment position, the range selected and the amount of direct contact must follow this distinction.
A sudden pop, immediate functional loss, inability to push off or perform a heel raise, a palpable tendon gap, marked swelling or bruising requires a rupture screen and urgent medical assessment. Massage is not the appropriate next step for an acute rupture pattern. Likewise, progressive severe pain, unusual rest or night pain, systemic features or symptoms that do not fit a mechanical loading pattern deserve broader medical consideration.
This clinical screen is not about making a medical diagnosis beyond scope. It is about knowing when the usual calf-and-tendon manual approach is inappropriate. A local trigger point response or a temporary change after pressure does not prove that one tissue was the sole source of posterior-ankle pain.
5. Achilles Pain Manual Therapy: Choose Contact and Re-Test Push-Off
When calf loading gives the clearest matching symptom, I use a supported position and tolerable contact along the identified gastrocnemius fibers or the accessible soleus region. Knee position, contact area and depth change with the tissue. I avoid strong direct pressure on an irritable tendon or its insertion.
If ankle dorsiflexion is the relevant finding, a qualified practitioner may trial mobilisation and compare the same heel-down tibial progression. For an assessed insertional tendon problem aggravated as the heel lowers, reconsider the starting range rather than automatically adding an off-step heel-drop programme. The Dutch multidisciplinary guideline advises considering a flat surface initially for insertional Achilles exercises, with the programme tailored to the individual. That is a starting option, not a permanent ban on dorsiflexion. When tendon loading best matches the complaint, symptom-relieving manual work remains an adjunct to progressive calf–tendon rehabilitation, not a substitute for capacity work.
Re-test the original straight- or bent-knee heel raise with the same support, heel height, speed and repetitions. Record whether pain occurs while lifting, holding or lowering the heel. If symptoms originally appeared during running, return only to an appropriate graded running assessment and identify the stance phase; a painless table examination alone does not demonstrate running tolerance. A short-term improvement supports the working hypothesis that the selected region influenced the painful task, but it does not prove the tendon, soleus or gastrocnemius was the sole cause or that capacity has been restored. Worsening load tolerance, acute functional loss or an atypical symptom pattern changes the plan toward medical assessment rather than stronger manual treatment.
Record the response after the agreed activity and again on the next morning’s first steps, including pain location, stiffness and whether ordinary walking or push-off is more difficult. Keep the activity and any load change in the record. Use this delayed response alongside the matched heel raise when reviewing the plan; an easier repetition immediately after contact is not, by itself, a reason to increase running load.
