Achilles Tendinopathy Causes, Symptoms & Treatments

What Is Achilles Tendinopathy?

Achilles tendinopathy refers to degeneration and thickening of the Achilles tendon—the band of tissue that connects your calf muscles to your heel bone (calcaneus). This tendon plays a vital role in daily activities such as walking, running, climbing stairs, and jumping.

Despite the old name “Achilles tendonitis”, the problem is usually not inflammation but overload: the tendon is asked to do more than it is currently conditioned for. It typically develops gradually over time, with micro-tears, collagen disorganisation and, in more advanced cases, calcification. That’s why effective treatment focuses on progressively rebuilding the tendon’s capacity—not simply resting it.

The two main types are treated differently:

• Mid-portion Achilles tendinopathy — pain 2–6 cm above the heel bone. The most common type, and the one standard loading programmes work best for.
• Insertional Achilles tendinopathy — pain right at the heel bone, often aggravated by uphill running, stairs, and shoes with a low heel. Loading is modified (e.g. heel raises on flat ground rather than off a step) to avoid compressing the tendon against the bone.

If not managed early, the condition can worsen, potentially leading to chronic pain or complete tendon rupture—both of which significantly impact mobility and quality of life.

Common Symptoms of Achilles Tendinopathy

The symptoms of Achilles tendinopathy can vary from mild discomfort to severe pain that limits daily activities. You may be experiencing this condition if you notice:

• Aching pain or stiffness in the back of the heel, especially after exercise
• Tenderness or swelling in the Achilles tendon area
• A bony lump at the back of the heel
• Reduced flexibility in the ankle joint
• Pain that worsens with physical activity and improves with rest
• Warmth or redness around the tendon

Early treatment can significantly reduce the risk of long-term damage.

What Causes Achilles Tendinopathy?

Achilles tendinopathy doesn’t typically occur from a single traumatic incident. Instead, it results from cumulative strain on the tendon, especially when:

• You increase your activity levels too quickly (e.g. running intensity or distance)
• You switch training surfaces abruptly (e.g. grass to concrete)
• You wear poor-fitting or unsupportive footwear
• Your calf muscles are tight, weak, or fatigued
• You skip proper warm-up and stretching routines
• You have a biomechanical issue (e.g. overpronation, leg length discrepancy)

Other contributing risk factors include:

• Age (commonly seen in people over 30)
• Obesity or excess body weight
• Diabetes or metabolic conditions
• History of lower limb injury
• High-impact sports like running, boxing, or basketball

At Flawless Feet, our podiatrists use biomechanical assessments to identify the root cause of your Achilles tendinopathy so treatment can be truly effective.

How We Treat Achilles Tendinopathy in London

Progressive tendon loading is the foundation of modern Achilles tendinopathy care — recommended in NICE and NHS guidance — with other treatments layered on top where they help. We customise each plan based on your activity level, goals, and severity of symptoms. Our approach is non-surgical, evidence-backed, and focused on settling pain, rebuilding tendon capacity, and preventing recurrence.

1. Biomechanical Assessment

We begin with a full analysis of your gait, posture, and lower limb alignment to pinpoint the imbalances and training errors that may be overloading the Achilles tendon.

2. Load Management & Progressive Exercise Programme

The evidence-backed core of your recovery. We reduce the load that’s aggravating the tendon, then rebuild its capacity step by step — starting with isometric holds to settle pain, and progressing to heavy slow resistance and eccentric calf raises. Expect this stage to run for 3–6 months: tendons adapt slowly, and consistency matters more than intensity.

3. Footwear, Heel Raises & Taping

Supportive, cushioned footwear suited to your foot type, a temporary heel raise to reduce the stretch on the tendon, and kinesiology taping to offload stress during activity — small changes that take strain off the tendon while it adapts.

4. Shockwave Therapy for Persistent Cases

Radial shockwave therapy for Achilles tendinopathy is typically reserved for cases lasting more than three months. It helps settle pain and stimulate tendon healing, and works best alongside your loading programme — not as a replacement for it.

5. Custom Orthotics

Where your foot mechanics are contributing to the strain, we design custom orthotic insoles that support the arch, correct foot posture, and reduce the load on the Achilles tendon.

6. Low-Level Laser Therapy (LLLT) as an Adjunct

LLLT can help settle pain and support tendon healing alongside your loading programme — a painless, no-downtime adjunct rather than a standalone fix.

7. Onward Referral

If your symptoms aren’t responding as expected, we arrange imaging (such as ultrasound or MRI) and, where appropriate, referral for further specialist input — so you’re never left without a clear next step.

What Happens If Achilles Tendinopathy Goes Untreated?

Ignoring Achilles tendinopathy can lead to worsening pain, reduced function, and an increased risk of partial or complete tendon rupture. This can require surgery and months of rehabilitation. Early intervention helps:

• Preserve tendon flexibility
• Avoid scar tissue build-up
• Maintain an active lifestyle
• Reduce the risk of re-injury

The longer tendinopathy goes unmanaged, the harder it becomes to treat. At Flawless Feet Podiatry & Laser Clinic in London, we aim to catch and correct issues early—before they escalate.
