Haglund's Deformity & Pump Bump Treatment
That painful bump at the back of the heel is rarely just a bony problem. We use diagnostic ultrasound to find which tissues are actually driving your pain, then treat the real cause.
What Is Haglund's Deformity?
Haglund's deformity is a bony enlargement of the back of the heel bone (calcaneus), at the posterosuperior corner just above where the Achilles tendon attaches. Because rigid-backed shoes press on this prominence, it picked up the nickname "pump bump", after the stiff court pumps that aggravate it.
The bony bump on its own is often painless. The pain usually comes from what sits between the bone and the tendon: the retrocalcaneal bursa (a small fluid-filled cushion that becomes inflamed when compressed) and the insertional Achilles tendon (which can degenerate where it meets the heel). When the bony prominence, the bursitis and insertional Achilles tendinopathy occur together, the combination is sometimes called Haglund's syndrome.
This distinction matters, because the most effective treatment targets the irritated soft tissue and the mechanical forces compressing it, not the bone itself. Finding a prominent heel shape on imaging does not automatically explain your pain, and surgery to reduce the bone is rarely the first or best answer.
Classic Symptoms
- A firm, often visible bump on the back of the heel, sometimes red or swollen
- Pain at the back of the heel that flares with stiff or rigid-backed shoes
- Tenderness just above the heel where the Achilles tendon attaches
- Stiffness and pain in the first steps in the morning or after rest
- Pain that worsens with hill running, sprinting or pushing off
Signs You Need Specialist Assessment
- Back-of-heel pain lasting longer than four to six weeks despite footwear changes
- Pain limiting your work, walking or training
- Marked swelling, warmth or redness over the bump
- A sense of weakness, or pain when rising onto your toes
- Diabetes, inflammatory arthritis or neuropathy, where heel pain can signal different pathology
Why the Bump Itself Is Rarely the Whole Story
Plenty of people have a prominent posterior heel and no pain at all. When the back of the heel does hurt, the pain generators are usually the retrocalcaneal bursa and the insertional Achilles tendon being squeezed between the bony prominence and the heel counter of a shoe.
That is why two patients with an identical-looking bump can need completely different treatment. One may have an inflamed bursa that settles quickly with offloading and a footwear change. Another may have established insertional Achilles tendinopathy that needs a structured loading programme and shockwave. Treating both the same way is how heel pain ends up dragging on for months.
Structures and conditions we check for:
- Retrocalcaneal bursitis: Inflammation of the bursa between the heel bone and the Achilles tendon. The most common early pain source.
- Insertional Achilles tendinopathy: Degeneration of the tendon at its attachment, often with calcification visible on imaging.
- Posterior (dorsal) calcaneal spur: A bony spur at the Achilles insertion, frequently seen alongside Haglund's.
- Superficial (subcutaneous) bursitis: Irritation between the skin and the tendon from direct shoe friction.
- Inflammatory enthesopathy: In psoriatic arthritis, reactive arthritis or ankylosing spondylitis, the Achilles insertion can be involved.
How We Diagnose Haglund's Deformity
Diagnostic Ultrasound Scanning
Every back-of-heel assessment at Lower Limb Clinic includes in-clinic diagnostic ultrasound. This lets us see the insertional Achilles tendon, the retrocalcaneal and superficial bursae and the bone surface in real time, during your first appointment, rather than weeks later after a separate referral.
We look for tendon thickening, hypoechoic (degenerative) change at the insertion, calcification, bursal fluid and increased blood flow on Power Doppler. Neovascularisation is a marker of active tissue pathology and helps us judge how irritable the tendon is and how to pace your loading programme.
Pressure Plate Gait Analysis
We map how force moves through your feet during standing and walking. A high-arched (cavus) foot, a stiff first ray or a tight calf complex all change how the Achilles insertion is loaded, and these patterns guide both orthotic prescription and your loading plan.
Clinical & Footwear Assessment
We assess ankle dorsiflexion (a tight calf is a key driver), heel alignment, tendon strength and the exact shoes you spend most time in. For Haglund's, footwear is often the single most modifiable factor, and identifying which shoes compress the prominence frequently produces fast relief.
Treatment Options
Around 90% of back-of-heel pain settles with structured non-surgical care. What we recommend depends on whether the main problem is bursitis, insertional tendinopathy, or both, and on the mechanics driving it.
Footwear Modification & Offloading
The fastest win for most patients. Switching to softer or open-backed heel counters, adjusting the heel tab and removing the compression on the prominence often reduces symptoms quickly.
Progressive Achilles Loading
For insertional tendinopathy, a graded heavy-slow or eccentric programme performed on a flat surface (avoiding the dropped-heel position that compresses the insertion) is the strongest evidence-based treatment.
Focused Shockwave Therapy (ESWT)
Strong evidence for insertional Achilles tendinopathy that has not responded to loading alone. Shockwave promotes tissue remodelling and reduces pain over a typical course of three to six weekly sessions.
Custom Orthoses & Heel Lift
A small heel lift reduces tensile load through the Achilles insertion, and custom orthoses (manufactured in-house via Réalta Labs using SLS 3D printing) address the cavus or asymmetric loading seen on gait analysis.
Activity & Load Management
Temporary reduction of the aggravating loads (hill running, sprinting, deep dorsiflexion) while symptoms settle, then a structured return to full activity rather than open-ended rest.
Surgical Referral When Indicated
For the minority who fail at least six months of structured conservative care, we refer to a trusted foot and ankle surgeon for consideration of bony resection or tendon debridement, with a clear rationale rather than as a first step.
A note on injections: corticosteroid injection directly into the Achilles insertion is generally avoided because of the risk to the tendon. Where an injection has a role, it is targeted and ultrasound-guided, and always combined with a loading programme.
Common Causes and Risk Factors
Haglund's deformity reflects the bony shape of the heel combined with the loads placed on it. Several factors raise the risk of it becoming painful.
Foot Type & Mechanics
A high-arched (cavus) foot tilts the heel and increases prominence of the posterosuperior calcaneus. A tight calf and reduced ankle dorsiflexion raise insertional load.
Footwear
Rigid or high heel counters (court pumps, ski boots, football boots, stiff dress shoes) compress the prominence and the bursa. This is the most modifiable factor.
Training Load
Rapid increases in running volume, hill work and sprinting load the Achilles insertion. Common in runners returning too quickly after a break.
Systemic Factors
Inflammatory arthropathies can drive insertional pain and enthesopathy, and should be considered when both heels are affected or symptoms are out of proportion.
What to Expect at Your First Appointment
Detailed history
5 minOnset, aggravating shoes and activities, previous treatment and impact on training and work.
Clinical examination
5–10 minHeel, ankle and calf examination including dorsiflexion range and Achilles strength.
Diagnostic ultrasound
10 minScanning the insertional tendon and bursae, shown to you in real time.

Diagnosis & treatment plan
5 minA clear diagnosis, footwear guidance and a personalised plan with realistic timelines.
Total appointment time is approximately 45 to 60 minutes. Most patients leave with a clear diagnosis, a footwear plan and treatment already underway.
Recovery and Prognosis
The outlook is good with the right diagnosis and a consistent plan. Bursitis driven mainly by footwear can settle within a few weeks once the compression is removed. Established insertional Achilles tendinopathy is slower and typically improves over 12 to 24 weeks of progressive loading, often supported by shockwave.
The biggest factors in recovery time are how long symptoms have been present before treatment, footwear, calf flexibility and consistency with the loading programme. We track progress with repeat ultrasound so decisions are based on measurable tissue change, not guesswork.
