Posterior Heel and Ankle Pain: Causes and Treatment Guide

Quick answer: Treatment for posterior heel ankle pain back of heel causes treatment follows a stepwise approach: 1) conservative care first (rest, ice, supportive footwear, OTC anti-inflammatories), 2) physical therapy and targeted exercises, 3) in-office treatments (injections, custom orthotics) if conservative fails at 4-6 weeks, 4) surgery for refractory cases. Most patients resolve at step 1 or 2. Call (810) 206-1402.

If you’ve felt a deep, gnawing ache at the back of your heel every time you take your first morning steps u2014 or a sharper, knife-like pain when you push off to climb a stair u2014 you are not alone, and you are not imagining it. We see posterior heel and back-of-ankle pain in our Howell and Bloomfield Hills clinics every single week. Patients describe it as “the back of the shoe is hitting bone,” “a pump bump,” “tendon stiffness that takes 20 minutes to walk off,” or “a deep bruise that won’t quit.” All of those descriptions point to the same neighborhood of structures, but the actual diagnosis dictates whether you need a heel lift, a boot, shockwave therapy, or surgery. Getting it right matters u2014 because the wrong stretch can make insertional Achilles tendinopathy worse, and a missed Achilles rupture can leave you with permanent calf weakness.

Why the back of your heel hurts

Back-of-heel pain is almost always caused by overload of one of three structures: the Achilles tendon insertion, the retrocalcaneal bursa, or the bony posterior calcaneus itself. The pain is usually worst with the first steps in the morning, after sitting, when wearing a stiff-counter shoe (dress shoes, ski boots, ice skates), or when pushing off to run uphill. Unlike plantar fasciitis u2014 which lives under the heel u2014 posterior heel pain points backward, where the heel meets the back of the shoe.

In our clinic, we sort patients into three buckets in the first 60 seconds. Bucket one: localized pain on the bony bump itself, worst with shoe pressure u2014 Haglund’s deformity or insertional tendinopathy. Bucket two: a soft, swollen, sometimes red lump just in front of the Achilles u2014 retrocalcaneal bursitis. Bucket three: tendon-belly pain 2u20136 cm above the heel u2014 non-insertional Achilles tendinopathy. Then we add the trauma question: did you feel a sudden “pop”? If yes, that is rupture until proven otherwise.

Anatomy: what’s actually back there

The back of your heel and ankle is a small, busy zone. The Achilles tendon u2014 the strongest tendon in the body u2014 inserts onto the middle third of the posterior calcaneus, transmitting forces up to 12.5 times body weight during running. Sitting between the tendon and the bone, just above the insertion, is the retrocalcaneal bursa, a fluid-filled cushion that lets the tendon glide. A second bursa u2014 the subcutaneous calcaneal bursa u2014 sits between the skin and the tendon, where shoe counters press. The posterosuperior calcaneal tuberosity is the bony prominence that, if enlarged, becomes Haglund’s deformity. Behind the lateral malleolus, the peroneal tendons pass; behind the medial malleolus, the posterior tibial, FDL, and FHL tendons pass with the tibial nerve and posterior tibial artery. The sural nerve hugs the lateral side of the Achilles u2014 entrapment here causes burning along the outside of the heel and into the little toe.

Insertional Achilles tendinopathy (#1 cause)

Insertional Achilles tendinopathy is degeneration and chronic inflammation at the spot where the Achilles attaches to the heel bone, usually with calcific spurring (a bone spur visible on X-ray). It accounts for roughly 50% of posterior heel pain in adults over 40. The hallmark is morning stiffness that loosens after a few minutes of walking, then a deep ache by late afternoon u2014 worse on hills, stairs, and stiff shoes. Examination reveals tenderness directly on the bony insertion, often with a palpable spur, and pain that worsens with single-leg heel-rise.

This is the diagnosis where the standard “Alfredson protocol” eccentric heel-drop u2014 dropping the heel below the level of the step u2014 actually makes things worse, because it stretches the inflamed insertion. The correct fix is the Jonsson modification: eccentric heel raises performed on flat ground only, never below neutral. Add a 1u20131.5 cm heel lift in both shoes (yes, both u2014 to keep the pelvis level), a stiff-soled rocker shoe, and avoid barefoot walking for 6 weeks. We see roughly 70% improve in 12 weeks with this regimen alone. For diabetic-collagen-quality patients or runners over 50, we add extracorporeal shockwave therapy (ESWT) at week 6 u2014 a 2024 systematic review showed 78% pain reduction at 6 months.

Surgical resection of the spur with reattachment of the tendon is reserved for failures past 6 months u2014 we use a central tendon-splitting approach with FHL transfer for patients over 50 or with greater than 50% tendon involvement, since the FHL augments the weakened tendon. Outcomes are 85u201390% return to recreational activity at 6u20139 months. Cortisone injection is contraindicated directly into the Achilles u2014 risk of rupture is real and well-documented.

Retrocalcaneal bursitis

Retrocalcaneal bursitis is inflammation of the deep bursa wedged between the Achilles tendon and the back of the heel bone. The pain is more posterolateral and posteromedial u2014 you can pinch the soft spot just in front of the tendon and reproduce the symptom. It often coexists with insertional tendinopathy and Haglund’s deformity in what’s called the Haglund triad. Causes include rigid shoe counters (dress shoes, ski boots, hockey skates), a tight gastroc-soleus complex, and a bony Haglund prominence that compresses the bursa with every step.

First-line treatment is mechanical: open-back shoes (clogs, slip-ons) or backless slippers at home, ice 15 minutes after activity, NSAIDs for 7u201310 days, and silicone heel cups that lift and offload. Topical Doctor Hoy’s Pain Relief Gel with menthol/MSM/arnica gives genuine analgesia without the GI risk of oral NSAIDs [available on Amazon]. We do not inject cortisone into this bursa u2014 too close to the tendon, too high a rupture risk. If conservative care fails at 12 weeks, ultrasound-guided aspiration with hyaluronic acid or PRP works in roughly 60% of stubborn cases. Surgical bursectomy is rare and almost always paired with Haglund resection.

Haglund’s deformity (pump bump)

Haglund’s deformity is a bony enlargement of the posterosuperior calcaneus u2014 the corner of the heel bone that sits where the back of the shoe presses. It is sometimes called a “pump bump” because high-heeled pumps were a classic culprit. Patients describe a hard, tender lump on the back-outer heel that hurts in any closed-back shoe. Imaging shows a prominent posterosuperior calcaneus with a parallel pitch line angle often greater than 75u00b0 or a Fowleru2013Philip angle greater than 75u00b0. It usually coexists with insertional tendinopathy and bursitis.

Conservative care works for 70u201380% of patients: open-back shoes, heel lifts, padding around the bump, and aggressive eccentric heel raises. PowerStep Pinnacle Maxx insoles with their built-in 6u00b0 heel lift offload the insertion beautifully [available on Amazon]. Surgical correction u2014 retrocalcaneal exostectomy with or without dorsal closing-wedge calcaneal osteotomy u2014 is reserved for failures, with 85u201390% satisfaction at 1 year. Endoscopic versions reduce recovery time but require a tighter pathology profile.

Sever’s disease (children 8u201314)

Sever’s disease u2014 properly called calcaneal apophysitis u2014 is the single most common cause of back-of-heel pain in active children ages 8u201314. It is an overuse injury of the cartilaginous growth plate at the back of the heel bone, where the Achilles inserts. The classic patient is an 11-year-old soccer or basketball player, often with a recent growth spurt and tight calves, who limps off the field after games and complains the heel hurts when squeezed from both sides (“squeeze test” positive). It is not a stress fracture u2014 the apophysis is normal physiology, just irritated.

Treatment is reassuring and effective: relative rest (cut sports volume by 50%, do not stop entirely), silicone heel cups in every shoe (including cleats), 6 weeks of daily gastroc-soleus stretching, ice after activity. Symptoms resolve completely as the apophysis fuses around age 14u201316. We do not immobilize, inject, or x-ray routinely u2014 X-rays look normal or show benign fragmentation that can scare families unnecessarily. The most important counseling point: this is self-limiting and benign, but the kid needs to do the heel cups and stretches consistently.

Non-insertional Achilles tendinopathy

Non-insertional Achilles tendinopathy is degeneration of the mid-portion of the tendon, classically 2u20136 cm above the heel. The tendon is thickened, tender, and sometimes nodular on palpation. This is the diagnosis where the classic Alfredson eccentric heel-drop protocol works u2014 3 sets of 15 reps, twice daily, for 12 weeks, performed on a step with the heel dropping below neutral. Multiple RCTs show 70u201380% improvement at 12 weeks with this protocol alone.

Risk factors include sudden increases in running volume, fluoroquinolone antibiotic use (ciprofloxacin, levofloxacin), corticosteroid injection nearby, statin use, and tight calf complex. Failures at 6 months get ESWT (78% response in our clinic), then PRP for stubborn cases, and only then surgery (longitudinal tenotomy with paratenon stripping, or gastrocnemius recession for the truly tight). We do not inject corticosteroid into the tendon u2014 ever u2014 and we counsel patients to stop fluoroquinolones at the first sign of tendon pain.

Achilles rupture (emergency)

Achilles tendon rupture is a same-day emergency. The classic story is a 35u201355-year-old “weekend warrior” who pushes off in a tennis or basketball game and feels “someone kicked me in the back of the leg” with an audible pop. Pain may be modest after the initial event u2014 the deceiving feature u2014 but the patient cannot push off, cannot do a single-leg heel rise, and the Thompson test is positive (squeezing the calf does not plantarflex the foot). A palpable gap is present in the tendon 2u20136 cm above the heel within the first 24 hours.

If you suspect rupture: stop walking, splint the foot in plantarflexion (toes pointed down), and call us at (810) 206-1402 or go to the ER. Treatment options are functional rehab in equinus (a CAM boot with progressive heel wedge removal over 8 weeks, suitable for low-demand patients) versus surgical repair (recommended for athletes and patients under 60 with high functional demands). Modern percutaneous and mini-open techniques have re-rupture rates around 2u20133%, comparable to functional rehab in well-selected patients but with faster return to play.

Calcaneal stress fracture

Calcaneal stress fractures account for under 10% of posterior heel pain, but they are the diagnosis you cannot afford to miss u2014 walking on one for weeks can convert it to a complete fracture. The classic patient is a military recruit, a sudden-onset distance runner, a postmenopausal woman with low bone density, or a patient on long-term steroids. Pain is diffuse across the entire heel, worse with weight-bearing, with a positive squeeze test from both sides of the heel (unlike Sever’s, which is age 8u201314). X-rays are normal for the first 2u20133 weeks; MRI is the diagnostic gold standard.

Treatment is a CAM walker boot for 4u20136 weeks, then progressive return to weight-bearing activity. We screen for stress-fracture risk factors aggressively: female athlete triad (low energy availability, menstrual dysfunction, low bone density), vitamin D deficiency, eating disorder, oral steroid use. A vitamin D level under 30 ng/mL roughly doubles the stress-fracture rate u2014 so we test it and supplement to a target of 40u201360 ng/mL.

Sural nerve entrapment

Sural nerve entrapment is rare but real u2014 typically a burning, tingling, or shooting pain along the lateral (outside) edge of the back of the heel, sometimes radiating to the little toe. It can develop after ankle sprain with scar tissue formation, after Achilles surgery, or with mass lesions (ganglion cyst, varicose vein) compressing the nerve. The Tinel sign u2014 tapping along the nerve reproduces the shooting pain u2014 is the bedside test. Ultrasound or MRI can identify a compressing structure. Treatment starts with neuromodulators (gabapentin, duloxetine), nerve glides, and addressing the structural cause; surgical decompression is reserved for confirmed entrapment refractory to 3 months of medical management.

How a podiatrist diagnoses back-of-heel pain

A focused 20-minute visit reaches the diagnosis 95% of the time. Here is exactly what we do, in order, in our Howell and Bloomfield Hills clinics:

1. Targeted history. Onset, trauma, “pop,” prior episodes, fluoroquinolone or statin use, sport, footwear, age (Sever’s vs adult disease).
2. Inspection. Looking for the bony bump (Haglund), the soft swelling (bursa), the cord nodule (tendinosis), bruising (rupture), redness/warmth (infection or gout).
3. Palpation map. Tender on the bone = insertional. Tender in front of tendon = bursa. Tender 2u20136 cm up = mid-tendon. Tender both sides squeezed = stress fracture or Sever’s.
4. Thompson test. Squeeze the calf with the patient prone u2014 absent plantarflexion = Achilles rupture, no further workup needed before urgent imaging.
5. Single-leg heel rise. Pain on rise = insertional or mid-tendon. Inability to rise = rupture.
6. Silfverskju00f6ld test. Differentiates isolated gastroc tightness from gastroc-soleus tightness u2014 changes treatment (gastroc recession vs full Achilles lengthening).
7. X-rays (lateral weight-bearing). Insertional spur, Haglund prominence, calcific tendinosis, parallel pitch line, Fowleru2013Philip angle. Sever’s apophysis appearance.
8. Ultrasound or MRI. Reserved for suspected partial rupture, chronic tendinosis with intrasubstance tear, mass lesion, suspected stress fracture (MRI), or pre-surgical planning.

Treatment ladder

Most posterior heel pain follows a predictable treatment ladder. We climb until the pain stops; most patients top out at rung 4u20136. The right rung depends on the diagnosis u2014 ruptures skip directly to splint or surgery, stress fractures skip directly to boot, but the rest of the diagnoses share this protocol.

1. Activity modification. Cut volume by 50% for 2 weeks; cross-train (bike, pool) instead of stop entirely.
2. Footwear correction. Open-back shoes for bursitis/Haglund; stiff rocker shoes for insertional tendinopathy; PowerStep Pinnacle Maxx insoles for support.
3. Heel lift. 1u20131.5 cm in both shoes for insertional disease and bursitis; reduces strain on the insertion by ~25%.
4. Eccentric protocol. Alfredson for mid-tendon, Jonsson modification (flat ground only) for insertional. 12 weeks minimum.
5. Topical analgesics. Doctor Hoy’s gel, ice 15 min after activity, NSAIDs 7u201310 days only.
6. Night splint. Stretches calf during sleep u2014 helps morning stiffness.
7. Custom orthotics. Considered when insoles fail or alignment issues coexist (overpronation, cavus foot).
8. Extracorporeal shockwave therapy (ESWT). 78% response at 6 months; covered out-of-pocket but durable.
9. Platelet-rich plasma (PRP). Reserved for chronic tendinosis after ESWT failure; mixed evidence but real responders.
10. Surgical decision. Tendon split + spur resection + FHL transfer for insertional; Haglund exostectomy + bursectomy for the bump; gastroc recession for the truly tight; tendon repair for rupture.

Red flags: when to be seen today

The most common mistake we see

The most common mistake we see is patients with insertional Achilles tendinopathy doing the YouTube-famous “drop your heel below the step” eccentric exercise. That protocol u2014 the original Alfredson u2014 was developed for mid-substance tendinopathy, where the tendon is 2u20136 cm above the heel. Dropping the heel below neutral with insertional disease drives the inflamed insertion into the bone spur on every rep. We’ve had patients spend 6 months making themselves worse with the wrong exercise. The fix is straightforward: insertional tendinopathy gets eccentric raises performed on flat ground only, never below neutral, and a heel lift in the shoe. If you’ve been doing the heel-drop for more than 4 weeks and the pain is the same or worse, please come in and let us look at your X-ray and re-direct your protocol.

Frequently asked questions

How long does back-of-heel pain take to heal?

For insertional Achilles tendinopathy and retrocalcaneal bursitis, expect 6u201312 weeks with appropriate eccentric exercise, heel lifts, and footwear correction. Sever’s disease in children resolves within 4u20136 weeks with relative rest and heel cups, but symptoms can recur during growth spurts until the apophysis fuses around age 14u201316. Achilles rupture takes 6u20139 months to return to sport. Calcaneal stress fracture heals in 4u20136 weeks in a CAM boot.

Should I keep running with back-of-heel pain?

If pain is mild (under 3/10), goes away within 30 minutes after running, and does not progress week to week, you can usually continue at a reduced volume. If pain is over 3/10, gets worse during the run, persists more than 24 hours afterward, or is accompanied by a “pop,” stop and get evaluated. Continuing to push through Achilles symptoms is the leading risk factor for converting tendinosis into a partial or complete rupture.

Is back-of-heel pain the same as plantar fasciitis?

No. Plantar fasciitis hurts on the bottom of the heel, where it meets the arch u2014 worst with first morning steps. Posterior heel pain hurts on the back of the heel, where it meets the shoe counter. They are different structures, different treatments, and different rehab protocols. Some patients have both at once u2014 if you do, address whichever is more painful first.

Will a cortisone shot help my back-of-heel pain?

For most causes, no u2014 and it can be dangerous. Cortisone injected into or near the Achilles tendon raises rupture risk significantly and is contraindicated. Cortisone into the retrocalcaneal bursa is occasionally done, but only with ultrasound guidance, only by experienced injectors, and only after conservative care has failed. We rarely do it. Better options are PRP, ESWT, or surgical correction depending on the underlying diagnosis.

What shoes are best for back-of-heel pain?

The right shoe depends on the diagnosis. For insertional tendinopathy and Haglund’s, look for open-back shoes (clogs, slip-ons, mules) at home and stiff rocker-soled walking shoes with a soft padded heel counter outside. Avoid pumps, ski boots, hockey skates, and rigid dress shoes during a flare. For mid-tendon tendinopathy, a maximalist running shoe with a higher heel-toe drop (10u201312 mm) reduces tendon strain. PowerStep Pinnacle Maxx insoles add a 6u00b0 heel lift inside any shoe.

When does back-of-heel pain need surgery?

Surgery is considered after 6 months of failed conservative care for insertional tendinopathy or Haglund’s deformity, immediately for displaced calcaneal stress fractures, and same-day for complete Achilles rupture in active patients. Modern procedures u2014 central tendon split with FHL transfer, retrocalcaneal exostectomy, percutaneous Achilles repair u2014 have 85u201395% satisfaction at 1 year. Recovery ranges from 3 months for simple bursectomy to 9 months for tendon transfer.

The bottom line

Back-of-heel pain has a short list of likely culprits, and the right diagnosis dictates the right treatment. Insertional tendinopathy responds to flat-ground eccentrics and a heel lift; mid-tendon disease responds to dropping the heel below the step; Sever’s resolves with a silicone heel cup; rupture needs same-day evaluation. The fastest path to relief is sitting in front of a podiatrist for 20 minutes and getting the diagnosis right u2014 not 6 months of YouTube exercises chasing the wrong protocol. Call us at (810) 206-1402 or book online and we’ll get you back on your feet.

Frequently Asked Questions

How long does treatment take to work?

Most patients see improvement in 4-8 weeks with consistent conservative care. Persistent symptoms after 8 weeks need imaging and escalation.

When is surgery needed?

Surgery is reserved for cases that fail 3-6 months of conservative care, structural deformities, or fractures requiring stabilization.

Is this covered by insurance?

Most diagnostic visits and conservative treatments are covered by Medicare and major insurers. Custom orthotics often require diabetic or post-surgical justification.

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.
