Retrocalcaneal Bursitis & Haglund's 2026 | DPM

Quick answer: Retrocalcaneal Bursitis Haglunds Deformity Heel Back Pain Michigan has multiple potential causes including mechanical, neurological, vascular, and inflammatory. The patterns we see most often are overuse, poorly-fitted shoes, and biomechanical imbalance. Red flags requiring urgent evaluation: warmth/redness (infection), inability to bear weight (fracture), and unilateral swelling without injury (DVT). Call (810) 206-1402.

What Is Retrocalcaneal Bursitis?

Retrocalcaneal bursitis is inflammation of the bursa sac located between the Achilles tendon and the posterior surface of the heel bone (calcaneus). This small fluid-filled sac normally reduces friction as the Achilles tendon moves during walking. When it becomes irritated and inflamed — from repetitive pressure, a rigid heel counter, a bony prominence (Haglund’s deformity), or tight calves — it causes pain and swelling directly at the back of the heel. At Balance Foot & Ankle in Howell and Bloomfield Hills, Michigan, Dr. Tom Biernacki, DPM treats retrocalcaneal bursitis conservatively and surgically when indicated. Call (810) 206-1402 for evaluation.

Haglund’s Deformity — The “Pump Bump”

Haglund’s deformity is a bony enlargement of the posterior superior calcaneus — the upper back corner of the heel bone. It is visible as a hard, prominent bump at the back of the heel and is often called a “pump bump” because rigid-heeled shoes (dress shoes, pumps, ice skates) press directly on it, aggravating the bursa and Achilles insertion. Haglund’s deformity is commonly seen in runners, figure skaters, and people who wear stiff-heeled footwear regularly. The combination of the bony prominence and reactive bursitis is called Haglund’s syndrome.

How to Tell the Difference: Retrocalcaneal Bursitis vs. Insertional Achilles Tendinopathy

Both conditions cause posterior heel pain but require different treatment approaches. Retrocalcaneal bursitis: soft, fluctuant swelling directly above the Achilles insertion; pain with shoe pressure on the upper heel; tenderness to deep palpation between the tendon and bone; MRI shows fluid in the bursa but intact tendon. Insertional Achilles tendinopathy: pain at the tendon-bone junction; morning stiffness that loosens with walking; tendon thickening on ultrasound; calcification within the tendon on X-ray. Many patients have both conditions simultaneously — accurate diagnosis via MRI directs the correct treatment pathway.

Conservative Treatment Protocol

First-line treatment for retrocalcaneal bursitis includes: heel lift inserts to reduce Achilles load and shift the heel away from the shoe counter (most effective initial intervention); footwear modification — open-back shoes or soft heel counters eliminate the direct pressure mechanism entirely; NSAIDs for acute flares; MLS laser therapy to reduce bursal inflammation without the risks of cortisone injection near the Achilles; and eccentric calf stretching in a pain-free range to improve Achilles flexibility. Cortisone injection into the retrocalcaneal bursa is effective for refractory cases but must be positioned precisely to avoid Achilles tendon injection — we use ultrasound guidance for all injections near the Achilles.

When Is Surgery Needed for Haglund’s Deformity?

Surgery is indicated for Haglund’s syndrome that has failed 4–6 months of comprehensive conservative treatment. The surgical procedure involves resection of the Haglund’s bony prominence (calcaneal exostectomy) with or without bursectomy. If significant insertional calcification is present, calcification excision may be performed simultaneously. Modern techniques include both open and endoscopic approaches. Recovery involves 2–4 weeks non-weight-bearing in a boot, followed by physical therapy. Most patients return to full activity by 3–4 months post-operatively.

Differential Diagnosis

Posterior heel pain has important differentials that change the treatment plan: insertional Achilles tendinopathy (within tendon substance, calcification on X-ray); Achilles tendon rupture (sudden pop, Thompson test positive — surgical emergency); calcaneal stress fracture (lateral squeeze test positive, history of sudden training increase); and Sever’s disease (calcaneal apophysitis in adolescents with open growth plates). Each requires a different approach — do not assume all posterior heel pain is Achilles-related without imaging.

Red Flags — Seek Same-Day Evaluation

Seek immediate evaluation for: a sudden “pop” at the back of the heel with inability to push off (Achilles rupture); inability to bear weight; spreading redness and warmth suggesting infection; a palpable gap in the Achilles tendon; or severe swelling developing within hours. These presentations require urgent assessment and should not be managed with home treatment alone.

Differential Diagnosis: What Else Could It Be?

Not every case of haglund’s deformity is straightforward. In our clinic we routinely rule out three look-alike conditions before confirming the diagnosis. If your symptoms don’t match the classic presentation, one of these may explain the pain — which is why physical exam matters more than self-diagnosis.

Condition	How It Differs
Retrocalcaneal bursitis alone	Anterior to the Achilles insertion, no posterior bone prominence.
Insertional Achilles tendinopathy	Pain at the tendon-bone junction; calcification may be present on X-ray.
Sever’s disease (pediatric)	Child or adolescent with growth-plate pain; Haglund presents in adults.

Frequently Asked Questions

When should I see a doctor?

See a podiatrist if pain persists past 2 weeks, prevents normal activity, or is accompanied by red-flag symptoms (warmth, swelling, numbness, inability to bear weight).

Can I treat this at home?

Mild cases respond to RICE protocol (rest, ice, compression, elevation), supportive shoes, and OTC anti-inflammatories. Persistent symptoms need professional evaluation.

How long does it take to heal?

Most soft tissue injuries resolve in 2-6 weeks with appropriate care. Bone injuries take 6-12 weeks. Chronic conditions need longer-term management.

What is Foot pain?

Foot pain is a common foot/ankle condition that affects mobility and quality of life. Understanding the underlying cause is the first step in successful treatment. Our podiatrists at Balance Foot & Ankle perform a hands-on biomechanical exam, review your activity history, and use diagnostic imaging when appropriate to identify the root cause—not just treat the symptom. Many patients have been told to “rest and ice” without a deeper diagnostic workup; our approach is different.

Symptoms and warning signs

Common signs of foot pain include pain that worsens with activity, morning stiffness, swelling, tenderness when palpated, and difficulty bearing weight. If you experience sudden severe pain, inability to walk, visible deformity, numbness or color change, contact our office the same day or visit urgent care—these can signal a more serious injury such as a fracture, tendon rupture, or vascular compromise. Diabetics with any foot wound should seek same-day care.

Conservative treatment options

Most cases of foot pain respond to non-surgical care: structured rest, supportive footwear changes, custom orthotics, targeted stretching and strengthening protocols, anti-inflammatory medications when medically appropriate, and in-office procedures such as ultrasound-guided injections. We also offer advanced therapies including MLS laser therapy, EPAT/shockwave, regenerative injections, and image-guided procedures. Treatment is sequenced from least invasive to most invasive, and we explain the rationale at every step.

When is surgery considered?

Surgery is reserved for cases that fail 3-6 months of well-structured conservative care, when there is structural pathology (severe deformity, complete tear, advanced arthritis), or when imaging shows damage that will not heal without intervention. Our surgeons have performed 3,000+ foot and ankle procedures and prioritize minimally-invasive techniques whenever appropriate. We discuss recovery timelines, return-to-activity milestones, and realistic outcome expectations before any procedure is scheduled.

Recovery timeline and prevention

Recovery from foot pain varies based on severity and chosen treatment path. Conservative cases often improve within 4-8 weeks with consistent adherence to the protocol. Post-procedural recovery may range from a few days (in-office procedures) to several months (reconstructive surgery). Long-term prevention involves footwear assessment, activity modification, structured strengthening, and regular check-ins with your podiatrist if you have a history of recurrence. We provide written home-exercise plans and digital follow-up support.
