Retrocalcaneal Bursitis: Symptoms, Causes, and Treatment

If the back of your heel feels like it’s protesting every stepespecially when your shoe collar even looks at it funnyyou might be dealing with
retrocalcaneal bursitis. It’s one of those injuries that sounds like a spell from a fantasy novel (“Retro-calcaneal… BUR-SI-TIS!”),
but it’s actually a very real (and very annoying) source of posterior heel pain.

The good news: most cases improve with smart, consistent conservative carethink better footwear choices, targeted stretching, and a temporary break from
whatever activity started the rebellion in the first place. The better news: you don’t have to “power through” pain at the Achilles insertion like it’s a
character-building exercise. It’s not. It’s just building inflammation.

What Is Retrocalcaneal Bursitis?

A bursa is a small, fluid-filled sac that helps tissues glide smoothly, acting like a cushion between moving parts. When a bursa gets irritated,
it can swell and become inflamedaka bursitis. Retrocalcaneal bursitis specifically involves the bursa located between the
Achilles tendon and the heel bone (calcaneus). This is why it’s often described as “Achilles tendon bursitis” or a type of
heel bursitis.

This area is a high-friction zone: you walk, run, climb stairs, jumpyour Achilles works overtime. If the bursa gets repeatedly compressed (by overuse,
stiff shoes, or a bony bump on the heel), it can inflame and complain loudly.

Symptoms: What It Feels Like (and What It Looks Like)

Retrocalcaneal bursitis usually shows up as pain at the back of the heel, near where the Achilles tendon attaches. Common symptoms include:

• Pain and tenderness in or behind the heeloften worse with walking or running
• Swelling and sometimes warmth/redness in the back-of-heel area
• Increased pain when standing on tiptoes or pushing off
• Pain that flares with ankle dorsiflexion (bringing your toes upward)
• Stiffness, a limp, or reduced ankle motion in some cases

A key clue: people often say normal shoes suddenly feel like they’re “attacking” the back of the heel. That’s not you being dramaticpressure and rubbing
from a stiff heel counter can irritate the area.

Red flag moment: if you have fever or signs of infection, it needs prompt medical evaluation. Both general bursitis guidance and retrocalcaneal-specific
resources note that infection is a possible cause and may require antibiotics.

Causes and Risk Factors: Why This Happens

Retrocalcaneal bursitis is usually a “too much, too soon” problem. The most common drivers are repetitive stress and mechanical irritationoften a combo.
Common causes and risk factors include:

1) Overuse and sudden training changes

Lots of running, jumping, long walks, or a sudden spike in activity can overload the Achilles/heel complex. A classic setup: you restart workouts with
heroic enthusiasm… and your heel responds with tragic realism.

2) Footwear friction and stiff heel counters

Tight or rigid shoes can rub the back of the heel and irritate the bursaespecially shoes with a firm collar. Some guidelines even suggest choosing shoes
that reduce direct pressure on the Achilles region.

3) Tight calves and Achilles overload

Tight calf muscles increase stress where the Achilles inserts into the heel. That extra tension can worsen irritation and contribute to posterior heel pain.

4) Haglund’s deformity (the “heel bump” problem)

Haglund’s deformity is a bony enlargement at the back of the heel that can rub against footwear and the Achilles region. It can be part of the mechanical
impingement that keeps the bursa inflamed.

5) Inflammatory conditions and crystal disease

Retrocalcaneal bursitis can also be associated with inflammatory arthritis (like rheumatoid arthritis) and crystal arthropathies (like gout or pseudogout).

6) Infection (less common, more urgent)

Bacterial infection can cause bursitis. If infection is suspected, clinicians may consider aspiration/testing of bursal fluid and treat with antibiotics.

Diagnosis: How Clinicians Confirm It (and Rule Out Look-Alikes)

Retrocalcaneal bursitis can resemble other causes of posterior heel painespecially insertional Achilles tendinopathy. In real life, they
can also show up together, which is why diagnosis often focuses on history, physical exam, and selective imaging.

What the exam usually includes

• Checking for swelling, warmth, and tenderness at the back of the heel
• Testing range of motion and pain provocation (like toe raises or ankle movement)
• Looking at footwear patterns and training history (the “what changed recently?” detective work)

Imaging and tests that may be used

Many cases are diagnosed clinically, but imaging can help confirm bursitis or exclude other causes. Common options include:

• X-rays to evaluate the heel bone and look for bony changes
• Ultrasound to visualize the bursa and nearby soft tissues
• MRI when clinicians need deeper detail or to assess other possible causes of heel pain

If infection is a concern, clinicians may aspirate fluid from the bursa for testing.

Treatment: What Actually Works

Most treatment plans are conservative at firstbecause in many cases, the bursa can calm down if you reduce the irritation and restore healthier mechanics.
The goal is simple: less friction, less compression, less inflammation.

Step 1: Calm the flare

• Rest / activity modification: temporarily stop or reduce the activity that triggers pain (often running or jumping), and consider switching
  to low-impact options if needed.
• Ice: short sessions (often up to ~20 minutes at a time) can help reduce pain and inflammation in the acute phase.
• NSAIDs (when appropriate): over-the-counter anti-inflammatory meds may help reduce pain/inflammation for some people, but they’re not for
  everyone (e.g., certain stomach, kidney, or cardiovascular risks).

Step 2: Fix the “why” (so it doesn’t keep coming back)

Footwear changes (the underrated hero)

If your shoe’s heel counter is stiff and high, it can keep poking the problem area like a tiny plastic villain. Adjusting footwear is often a big deal.
Options may include shoes that reduce pressure on the back of the heel, or modifying the heel collar shape to avoid rubbing.

Heel lifts and wedges

A modest heel lift can reduce tension at the Achilles insertion. Some patient handouts for posterior heel pain specifically note that walking barefoot or in
very flat shoes can increase tension, while a moderate heel can reduce stress and irritation.

Orthotics

Heel wedges or orthotics can reduce irritation and improve walking mechanics. Some people do well with store-bought options; others need custom inserts.

Stretching and physical therapy

Physical therapy often focuses on Achilles/calf flexibility and strength, which can decrease stress on the irritated bursa and improve overall function.
Expect a mix of stretching, strengthening, and sometimes manual therapy or other modalities.

One key note: if you also have insertional Achilles tendinopathy, your clinician or PT may adjust exercises to avoid excessive compression at the tendon
insertion while you’re flared.

Step 3: If it’s stubborn, escalate carefully

Temporary immobilization

In more painful casesor when symptoms won’t settleshort-term use of a brace, boot, or cast may be recommended to reduce movement and allow the area to
calm down.

Antibiotics (only if infection is involved)

If the bursitis is caused by infection, treatment may include antibioticsand the evaluation may involve aspiration/testing.

Corticosteroid injections: helpful for some, but not casual

Steroid injections into the bursa are sometimes used in select cases to reduce inflammation, but they’re typically not a first-line move. Multiple medical
sources caution that injections around the retrocalcaneal region can carry a risk of Achilles tendon injury or rupture, so clinicians weigh risks carefully
and may use ultrasound guidance.

Practical takeaway: if an injection is offered, ask about technique (often image guidance), what to avoid afterward, and whether there are signs of tendon
compromise. Some procedural guidance notes that a partial Achilles tear can be a relative contraindication to steroid injection because it may increase the
risk of tear progression.

Surgery (rare, but real)

Surgery is usually reserved for persistent cases that don’t improve after an extended period of conservative treatment. Procedures may involve removing the
inflamed bursa (bursectomy) and, when a bony prominence contributes to mechanical irritation, addressing that as well.

Recovery Timeline: How Long Does It Take?

The honest answer: it depends on what’s driving the irritation (training error vs. footwear vs. Haglund’s deformity vs. inflammatory disease) and how well
the mechanical triggers get addressed.

Many people improve within a few weeks of consistent home care, while more severe or persistent cases can take monthsespecially if you keep testing the heel
by returning to high-impact activity too quickly.

Prevention: Keep Your Heel From Filing Another Complaint

• Increase activity gradually (your Achilles is not impressed by sudden ambition).
• Warm up and stretch, especially calves and ankle mobility.
• Choose shoes wiselyavoid stiff heel counters that rub the back of the heel.
• Address tight calves early with a stretching/strength plan.
• Manage underlying conditions (like gout or inflammatory arthritis) with your clinician if relevant.

When to See a Clinician

Consider medical evaluation if pain is severe, you can’t bear weight, symptoms keep returning, you suspect infection (fever, increasing redness/warmth), or
you’re not improving after a reasonable trial of conservative care. Clinicians may use imaging (X-ray, ultrasound, MRI) to confirm the diagnosis or rule out
other causes of heel pain.

Common Questions (Quick, Useful Answers)

Is retrocalcaneal bursitis the same as Achilles tendinitis?

Not exactly. Retrocalcaneal bursitis is inflammation of the bursa between the Achilles and heel bone; Achilles tendinitis/tendinopathy involves the tendon
itself. They can occur together, and the symptoms overlap, which is why clinicians evaluate both tendon and bursa.

Should I stretch through the pain?

Stretching can help long-term, especially for tight calves, but aggressive stretching during a flare can aggravate symptomsparticularly if the tendon is
irritated too. A PT-guided plan is often the safest way to progress.

Do I need surgery?

Most people don’t. Surgery is generally considered only after prolonged conservative care fails, or when mechanical factors (like significant bony
prominence) keep the area irritated.

Conclusion

Retrocalcaneal bursitis is a classic “posterior heel pain” culpritoften driven by overuse, footwear friction, tight calves, or mechanical impingement near
the Achilles insertion. The best outcomes usually come from a one-two punch: calming the inflammation (rest/ice/appropriate meds) and fixing the trigger
(shoe changes, heel lifts/orthotics, and a smart strengthening/stretching plan). And if your heel’s getting hot, red, and you’re running a fever, don’t
self-diagnose your way into troubleget evaluated.

Real-World Experiences: What People Commonly Notice (and What Helps)

Let’s talk about the part that doesn’t show up on an X-ray: the day-to-day experience. People with retrocalcaneal bursitis often describe a very specific
frustration patternpain that’s not always dramatic at rest, but shows up the moment you try to live your normal life. The heel might feel “tight,” “bruised,”
or like there’s a small, angry marble wedged behind the Achilles. The first few steps after sitting can feel especially rude. Then you warm up and think,
“Oh, I’m fine.” Spoiler: you’re not fine. You’re just temporarily distracted by movement.

One of the most common experiences is the shoe dilemma. A lot of people can walk around the house barefoot and feel okay, but the second they put on a shoe
with a stiff heel counter, it’s like their heel sends a formal complaint to HR. That’s why simple footwear experiments can be surprisingly revealing:
swapping to a softer-backed shoe, using a heel lift, or choosing a shoe with a cutout around the Achilles area often changes symptoms quicklyeven before the
inflammation fully resolves.

Another common theme: people underestimate the impact of calf tightness until they start working on it consistently. The first week of gentle calf work can
feel like nothing’s happeningthen suddenly it’s easier to get through a normal day without that constant “back of heel” tug. The best results usually come
when stretching is paired with strengthening and done with enough patience to let tissues adapt, not panic.

Here are a few “composite examples” (typical scenarios, not real patients) that match what clinicians see all the time:

• The weekend warrior runner: goes from 2 miles twice a week to training for a 10K in two weeks. The heel swells, shoes hurt, toe-offs feel sharp.
  Once they cut mileage, cross-train, fix shoes, and build calf strength gradually, symptoms settle.
• The new job on hard floors: starts standing all day, wears dress shoes with firm backs, and develops tenderness and swelling behind the heel.
  Switching footwear and adding heel support reduces irritation while they build tolerance.
• The “mysterious bump” heel: has a noticeable heel prominence that rubs every shoe. They improve with heel lifts and shoe changes, but flare repeatedly.
  That’s when clinicians consider whether Haglund’s deformity is a key driver.

The emotional experience is real, too. Retrocalcaneal bursitis is the kind of problem that makes people feel “behind” because it limits basic activity:
walking the dog, errands, workouts, even standing to cook dinner. A helpful mindset is treating rehab like a boringbut effectivesubscription service:
small payments (ice, shoe tweaks, exercises, rest days) made consistently beat one giant “hero workout” followed by a week of regret.

If you do need next-level treatment, many people report relief from formal physical therapy because it turns vague advice (“stretch more”) into a plan with
progression. And if injections are discussed, people often feel anxious (fair!) because of the Achilles’ importance. That’s why it’s worth asking questions
about risks, image guidance, and what activity restrictions followespecially since some sources highlight rupture risk and contraindications in certain tendon
situations.

Bottom line from the lived-experience angle: most people do best when they stop negotiating with pain, remove the mechanical trigger (usually shoes/training
load), and commit to a gradual return. Your heel isn’t trying to ruin your lifeit’s just asking you to stop treating it like a crash-test dummy.
