Retrocalcaneal bursitis is a painful inflammatory condition at the back of the heel where the retrocalcaneal bursa sits between the Achilles tendon and the heel bone (calcaneus). Bursae are small, fluid-filled sacs that reduce friction and act like a cushion where tissues glide over each other. When the retrocalcaneal bursa becomes irritated by repeated load, compression, or impingement, it can swell and become painful, making walking, running, and shoe wear uncomfortable.
This condition often overlaps with insertional Achilles pain and can be part of a broader picture sometimes referred to as Haglund syndrome (where bursal irritation occurs with a prominent posterosuperior calcaneus and Achilles insertion irritation). People commonly notice pain at the back of the heel that is worse in closed-in shoes, after hill walking, after running, or when the ankle is repeatedly pushed into dorsiflexion (the ankle bending upwards), which increases compression between the Achilles tendon and the calcaneus.
Physiotherapy for retrocalcaneal bursitis focuses on reducing compressive irritation, improving the Achilles and calf complex capacity to handle load, and modifying the factors that keep pinching or aggravating the bursa. Unlike mid-portion Achilles tendinopathy where tendon loading is the main focus, retrocalcaneal bursitis rehab often hinges on load management plus compression management. Your physiotherapist will guide footwear changes, heel lifts or orthoses when appropriate, and a strengthening program that builds resilience while avoiding positions that excessively compress the painful area.
Key Facts
- The retrocalcaneal bursa is located between the anteroinferior Achilles tendon and the posterosuperior calcaneus, and inflammation here is a recognised cause of posterior heel pain and part of Haglund syndrome. 🔗
- In an image-guided injection study, 63% of patients had a significant short-term decrease in pain after retrocalcaneal bursa corticosteroid injection, and the subsequent Achilles tendon rupture rate was 1.8%. 🔗
- Retrocalcaneal bursitis may be secondary to overuse, inflammatory or crystalline arthropathy, infection, or mechanical impingement such as Haglund deformity, and Achilles tendinopathy commonly occurs concurrently. 🔗
- A runner case-control study (30 with prior retrocalcaneal bursitis and 30 controls) investigated calcaneal tuberosity shape as a factor associated with the occurrence of retrocalcaneal bursitis in regular runners, highlighting the role of posterior heel anatomy and compression in some people. 🔗
Risk Factors
- Sudden increase in running, jumping, hill work, or standing and walking volume.
- Footwear with a rigid or tight heel counter that increases posterior heel pressure.
- Reduced calf flexibility or ankle mobility leading to altered heel loading and increased compression.
- A prominent posterosuperior calcaneus or mechanics that increase Achilles compression at the insertion.
- Systemic inflammatory or crystal arthropathies such as rheumatoid arthritis or gout.
- Older age and reduced Achilles tissue elasticity, which can increase sensitivity to load changes.
Symptoms
- Pain at the back of the heel, typically deep to the Achilles tendon and worse with walking, running, or hills.
- Swelling around the posterior heel, often just in front of the Achilles tendon.
- Tenderness when pressing the area, sometimes especially when the heel is pinched from both sides.
- Stiffness around the ankle, particularly after rest or first thing in the morning.
- Pain aggravated by closed-in shoes, rigid heel counters, or footwear that rubs the back of the heel.
- Redness and warmth over the back of the heel during a stronger inflammatory flare.
- Reduced tolerance to jumping, sprinting, and pushing off the toes.
Aggravating Factors
- Running and jumping, particularly hills, speed work, and increased training volume.
- Walking uphill or climbing stairs, which increases Achilles demand.
- Activities that repeatedly bend the ankle upward (dorsiflexion), increasing compression between the Achilles and heel bone.
- Tight or stiff-backed shoes that press on the back of the heel.
Causes
Retrocalcaneal bursitis usually develops from a combination of load and compression at the back of the heel. The bursa sits in a tight space between the Achilles tendon and the calcaneus. When the Achilles tendon is repeatedly loaded (for example with running, jumping, or hill walking) and the ankle repeatedly moves into positions that compress the space (especially dorsiflexion), the bursa can become irritated and inflamed.
Footwear can also be a major driver. Shoes with a rigid heel counter, tight lacing, or a high back can increase direct pressure and irritation around the posterior heel. In some people, a prominent posterosuperior calcaneus (often discussed in the context of Haglund-related issues) increases the likelihood of mechanical impingement. The end result is swelling, pain, and sensitivity that can make it hard to comfortably wear shoes or tolerate sport.
Retrocalcaneal bursitis may also be associated with systemic inflammatory or crystal arthropathies such as rheumatoid arthritis or gout, where inflammation can affect bursae and surrounding tissues. Less commonly, infection can be a cause, particularly if there is significant redness, warmth, systemic symptoms, or a history of skin breakdown.
Physiotherapists treat retrocalcaneal bursitis by identifying which combination of compression, training load, footwear, and biomechanics is driving the problem, then addressing those factors while rebuilding the lower limb’s capacity to handle load.
How Is It Diagnosed?
Retrocalcaneal bursitis is usually diagnosed clinically by a physiotherapist or doctor based on your symptoms and examination. Your physiotherapist will ask about training changes, hill running, recent footwear changes, and whether pain is worse in shoes or in activities that bend the ankle upwards. On examination, they will check the exact pain location, swelling patterns, calf flexibility, ankle mobility, and Achilles tendon loading tolerance.
A key part of diagnosis is distinguishing retrocalcaneal bursitis from other causes of posterior heel pain, such as insertional Achilles tendinopathy, superficial Achilles bursitis (subcutaneous bursa), Haglund-related impingement, stress injury, or less common inflammatory or infectious causes. If symptoms are severe, unusually hot or red, associated with fever, or not responding as expected, medical review is important.
Because retrocalcaneal bursitis is influenced strongly by compression, your physiotherapist will also assess which positions and movements reliably flare symptoms. This helps guide the rehab plan, particularly the selection of stretching and strengthening strategies that improve function without repeatedly pinching the bursa.
Investigations & Imaging
- Ultrasound
- Can identify bursal fluid and thickening, and can also assess the Achilles insertion and guide aspiration or injection when indicated.
- MRI
- Shows the retrocalcaneal bursa as an enlarged fluid-filled structure and helps assess associated Achilles insertion pathology when the diagnosis is unclear or symptoms persist.
- X-ray
- May identify a prominent posterosuperior calcaneus or other bony contributors to impingement and helps rule out alternative pathology when clinically indicated.
Physiotherapy Management
Physiotherapy for retrocalcaneal bursitis aims to reduce bursal irritation and restore the Achilles complex’s ability to tolerate load without repeated compression.
Treatment is typically individualised around two levers:
- Reducing the compressive position and pressure that pinches the bursa, and
- Progressively reloading the calf and Achilles so normal walking, running, and sport become comfortable again.
Your physiotherapist will usually address footwear and training loads early because these are common reasons symptoms persist. Rehab then focuses on building strength and movement control through the ankle and foot, while avoiding aggressive stretching that pushes the ankle into deep dorsiflexion if that consistently compresses the bursa. A good plan improves function without triggering a cycle of flare, rest, and re-flare.
Exercise
Exercises are chosen to build calf and Achilles capacity while keeping the bursa calm. Early on, your physiotherapist may use isometric calf exercises (such as holding a heel raise position) because this can load the Achilles without large ankle movement. This is particularly useful when deep ankle bending is the main irritant.
As pain settles, exercises progress to slow, controlled calf strengthening, often starting on flat ground rather than on a step. This detail matters in retrocalcaneal bursitis rehab because heel drop over a step increases dorsiflexion and can increase bursal compression. Your physiotherapist may use a gradual progression from double-leg heel raises to single-leg heel raises, then to heavier strengthening, guided by how symptoms respond over 24 hours.
Foot and ankle control exercises are often included to reduce excessive heel shear and improve shock absorption, especially for runners. Later-stage rehab may include carefully graded plyometrics and return-to-running drills, introduced only when daily walking and strengthening are comfortable and the posterior heel is not reactive.
Activity Modification
Activity modification is essential for settling retrocalcaneal bursitis. Your physiotherapist will help you reduce the specific activities and positions that compress the bursa, often including hills, speed work, jumping, deep squats, and stair volumes early in recovery. Many people can maintain fitness with cycling or swimming while impact is reduced, which keeps overall conditioning up without repeatedly flaring the heel.
Footwear is part of activity modification. Switching out of rigid heel counters, using shoes with a slightly higher heel-to-toe drop, and avoiding tight lacing can quickly reduce pressure on the irritated area. Your physiotherapist will then guide a gradual return to running or sport with planned progressions, rather than returning suddenly once pain feels a little better.
A practical rehab rule used in physiotherapy is monitoring the next-day response. If the heel is significantly more painful or swollen the day after an activity, the load was too high and needs adjustment.
Manual Therapy
Manual therapy may be used to improve ankle and calf mobility where stiffness is contributing to poor mechanics, but it is applied with the compression issue in mind. For retrocalcaneal bursitis, the goal is not to force the ankle into deep dorsiflexion if that pinches the bursa. Instead, physiotherapists often work on calf soft tissue flexibility and ankle joint mobility in ranges that improve gait efficiency without reproducing strong posterior heel compression.
Manual therapy can also be used for pain modulation, helping you tolerate walking and strengthening. It is typically most effective when paired with load management and progressive strengthening so improvements translate into better function.
Postural Retraining
Postural retraining for retrocalcaneal bursitis is usually gait and movement retraining. Many people avoid heel loading by turning the foot out, shortening stride, or walking on the forefoot. This can overload the calf, Achilles, or the other leg. Your physiotherapist will help restore a comfortable walking pattern and improve single-leg control so the heel is loaded smoothly without excessive shear.
For runners, retraining might include reducing overstriding, managing cadence, and controlling hill exposure early. The goal is to reduce repeated posterior heel compression while maintaining running capacity.
Bracing & Taping
Bracing and taping may be used to reduce irritation during the settling phase. Some people benefit from taping to reduce strain on the Achilles insertion and improve comfort in shoes. A heel lift (temporary) is commonly used to reduce dorsiflexion and compression at the back of the heel, which can be particularly helpful in retrocalcaneal bursitis where pinching is a key driver.
Orthotics may be recommended when foot mechanics are contributing to excessive Achilles insertion stress or poor shock absorption. The aim is to reduce repeated irritation and allow strengthening to progress. Your physiotherapist will trial and adjust supports carefully, because overly rigid devices can sometimes create new pressure points or change loading in unhelpful ways.
Heat & Ice
Ice is commonly used to help settle pain and swelling in retrocalcaneal bursitis, particularly after activity. Your physiotherapist may recommend short applications after aggravating tasks. Heat is less commonly used over an inflamed bursa, but may be used for calf muscle tightness if stiffness is limiting movement quality.
Tens
TENS may be used as a pain management tool when posterior heel pain is limiting walking, sleep, or rehab participation. In physiotherapy, it is used as an adjunct so you can stay active and keep strengthening, rather than as a primary treatment.
Education
Education is central to retrocalcaneal bursitis rehab. Your physiotherapist will explain the difference between compression-driven pain and pure overuse pain, and why certain stretches and positions can be counterproductive early on. Education includes shoe selection, how to lace shoes to reduce heel pressure, how to modify hills and speed work, and how to pace return to impact.
You will also learn practical flare management strategies, including how to adjust load based on next-day symptoms. This helps prevent the stop-start cycle that often prolongs heel problems.
Other
Other physiotherapy management may include a return-to-run program, conditioning alternatives during impact reduction (cycling, swimming), and coordination with your GP if inflammatory conditions are suspected. If your physiotherapist suspects significant Achilles insertion involvement, they may tailor the strengthening plan accordingly and recommend imaging or specialist review when appropriate.
Other Treatments
Other treatments may include short-term use of anti-inflammatory medication as advised by your GP, and in selected cases image-guided corticosteroid injection into the retrocalcaneal bursa. Injections can reduce pain for some people, but they must be considered carefully because injecting close to the Achilles tendon can carry risks, including tendon weakening and rupture. For this reason, physiotherapy and footwear modification are usually prioritised first, with injections reserved for persistent cases and performed using appropriate technique and guidance when chosen.
If a systemic inflammatory condition such as rheumatoid arthritis or gout is suspected, medical management of the underlying condition is important alongside physiotherapy, because ongoing inflammation can keep the bursa reactive.
Surgery
Surgery for retrocalcaneal bursitis is uncommon and is usually considered only when conservative management has been comprehensive and symptoms remain significantly limiting. Surgical procedures may include removal of the inflamed bursa (bursectomy) and, when relevant, addressing contributing bony impingement (for example calcaneal prominence) and associated Achilles insertion pathology.
If surgery is performed, post-operative physiotherapy is important to restore ankle mobility, rebuild calf strength, retrain gait, and guide a graded return to activity while protecting healing tissues.
Prognosis & Return to Activity
Most people recover well from retrocalcaneal bursitis when the main irritants are identified and managed. Mild cases can settle over weeks, particularly when footwear pressure is reduced and training loads are modified early. More persistent or chronic cases can take months, especially if the posterior heel continues to be compressed by shoes, hills, or aggressive stretching into dorsiflexion.
Return to activity is usually guided by function-based milestones: comfortable walking in normal shoes, reduced swelling after daily tasks, the ability to perform calf strengthening without next-day flare, and gradual reintroduction of running and jumping without worsening symptoms. Your physiotherapist will plan this progression and adjust it based on how the heel responds over 24 hours.
If symptoms are not improving as expected, reassessment is important to confirm whether the bursa is the primary source of pain or whether insertional Achilles pathology, bony impingement, or inflammatory disease is contributing.
Complications
- Persistent posterior heel pain and swelling if compression and load triggers are not addressed.
- Reduced tolerance to running and jumping due to ongoing Achilles insertion irritation.
- Progression to more complex posterior heel pain presentations involving both the bursa and Achilles insertion.
Preventing Recurrence
- Avoid repeated deep ankle dorsiflexion loading early if it triggers bursal pinching. Build strength first, then reintroduce deeper ranges gradually as tolerated.
- Choose footwear that reduces heel counter pressure. A softer heel collar or slightly higher heel-to-toe drop can reduce posterior heel compression during flare-prone periods.
- Progress hills and speed work gradually. Sudden increases in hill running are a common way to overload the Achilles insertion and irritate the retrocalcaneal bursa.
- Maintain calf strength year-round. Strong calves improve shock absorption and reduce the likelihood the posterior heel becomes reactive when training increases.
When to See a Physio
- If posterior heel pain is limiting walking, running, or shoe wear for more than 1 to 2 weeks.
- If there is significant redness, warmth, fever, or rapidly increasing swelling, as infection or inflammatory flare may require urgent medical review.
- If pain is persistent despite footwear changes and rest, as you may need a structured retrocalcaneal bursitis physiotherapy plan.
- If you have a history of rheumatoid arthritis or gout and new posterior heel swelling, as systemic causes may need medical management alongside physiotherapy.
