Achilles Tendinopathy: Heel Pain, Causes, Treatment and Support

Pain at the back of the heel, stiffness on the first few steps and soreness after running can come from Achilles tendinopathy. The Achilles connects the calf muscles to the heel and helps you push off when walking, climbing stairs or jumping. Symptoms often develop when repeated loading exceeds what the tendon currently tolerates.

Location and symptoms matter

Midportion symptoms occur above the heel attachment; insertional symptoms occur where the tendon meets the heel bone. Morning stiffness, tenderness, thickening and activity-related pain are common. A sudden training increase, tight calves or a footwear change can contribute. Shoe pressure may particularly irritate the heel attachment.

A sudden pop with abrupt pain or loss of push-off strength needs urgent assessment for a possible rupture. That is a different problem from gradually developing tendinopathy. The AAOS Achilles guide explains these distinctions.

Diagnosis and treatment options

A clinician considers the pain location, activity history, tenderness and tendon function. Imaging may clarify uncertain findings or the extent of damage, but an MRI is not automatically needed for a typical presentation.

Most treatment begins without surgery. Options include changing provocative activity, rehabilitation, footwear adjustments and selected temporary supports. Persistent symptoms may prompt discussion of shockwave treatment or surgery after an adequate nonsurgical program. Platelet-rich plasma injections have uncertain benefit. Steroid injections around the Achilles are generally avoided because of tendon-tear risk.

The treatment should also reflect whether the pain is at the insertion or farther up the tendon; an exercise copied from a different diagnosis may be unsuitable. AOFAS FootCareMD outlines assessment and options for non-insertional symptoms.

Progressive loading is the foundation

For midportion tendinopathy, the 2024 clinical guideline recommends tendon-loading exercise as first-line care. The aim is to rebuild capacity with an appropriate, progressively challenging program, rather than rely on complete rest. Activity can usually continue within an agreed symptom tolerance.

A physiotherapist can adjust calf exercises, resistance and movement range to your starting point. The same program is not appropriate for every person or every tendon location. Heel lifts may temporarily reduce how far the ankle bends upward during activity. Evidence for routine foot orthoses in midportion tendinopathy remains inconsistent.

Education and loading should work together: understand which activities provoke symptoms and how to modify them while maintaining useful movement. See the 2024 JOSPT guideline.

Managing work, exercise and expectations

Meaningful improvement commonly takes months. A sustainable strengthening routine is therefore more useful than repeatedly stopping and restarting whenever the tendon feels better for a day. Low-impact exercise can help maintain fitness while more demanding loading is temporarily reduced.

At work, identify the tasks that repeatedly trigger symptoms and discuss realistic adjustments. In training, change the amount or intensity that is provoking pain while following the rehabilitation plan. If symptoms increase rather than settle as the program progresses, review the exercise load with your physiotherapist.

The Berkshire Healthcare NHS patient leaflet emphasizes progressive strengthening and a gradual return to activity.

Which support actually matches the problem?

A product labeled “ankle support” does not necessarily address Achilles loading. Read its construction and intended use before choosing:

• Heel lift or footwear modification: a targeted option to discuss when tendon loading or shoe contact is the main issue.
• Compression sleeve: a soft layer, without the positioning or immobilization of a medical boot.
• Lace-up ankle brace: designed primarily around ankle support; it is not a replacement for tendon rehabilitation.
• Prescribed walking boot: a separate treatment tool used for selected problems under a defined plan.

If you also experience ankle rolling, compare ankle support structures for that additional need. Do not select a generic brace solely because Achilles pain appears in a product keyword list. At follow-up, describe the exact painful location, morning stiffness and changes after activity; these details are more useful than a general report of “ankle pain.”
