Pain at the back or underside of the heel can make ordinary steps, workouts, and time on your feet surprisingly difficult. Because several conditions can feel similar, the location and pattern of discomfort matter, but they do not confirm a diagnosis on their own.
Heel bursitis is inflammation of a small, fluid-filled sac that cushions moving tissues near the heel. When the retrocalcaneal bursa is involved, irritation occurs between the Achilles tendon and heel bone, which may cause localized pain, tenderness, stiffness, swelling, or redness. (Sources: Mayo Clinic; PubMed.)
Rest, activity changes, supportive footwear, and other conservative measures may help in some cases, while persistent or severe symptoms deserve professional evaluation. Understanding the bursa’s position is the first step toward recognizing why this pain can be confused with plantar fasciitis, Achilles tendon problems, or other heel conditions.

What Is Heel Bursitis and Where Does It Hurt?
A bursa is a small, fluid-filled sac that cushions moving tissues, helping bones, tendons, and muscles move with less friction. Bursitis develops when one of these sacs becomes inflamed. In the heel, the irritated bursa may be near the back of the ankle, where several structures move together during walking and activity. Mayo Clinic explains how bursae cushion nearby bones and soft tissues.
One specific form is called retrocalcaneal bursitis. The retrocalcaneal bursa sits between the Achilles tendon and the calcaneus, the medical name for the heel bone. Because this is a relatively confined space, pressure or irritation around the Achilles tendon can affect the bursa. The discomfort is usually felt at the back of the heel, close to where the Achilles tendon attaches to the heel bone, rather than primarily along the bottom of the foot. The anatomy is described in this medical review of retrocalcaneal bursitis.
People may describe the area as sore, achy, stiff, or tender when touched or when the ankle moves. Swelling or redness can also occur. Pain may become more noticeable when the back of a shoe presses against the heel, although symptoms vary from person to person. These signs can overlap with Achilles tendon problems, irritation from a prominence at the back of the heel, or other causes of heel pain. They do not confirm bursitis by themselves.
Heel pain deserves an evaluation when it persists, limits normal activity, or keeps returning. A podiatric examination can help identify which structure is involved and guide the next step without assuming a diagnosis from symptoms alone.

What Causes Heel Bursitis?
Heel bursitis can develop when a bursa near the heel is repeatedly compressed or irritated. Bursae are small, fluid-filled sacs that help reduce friction between moving tissues. At the back of the heel, the retrocalcaneal bursa sits between the Achilles tendon and the heel bone. Because it occupies a relatively confined space, pressure from the tendon or surrounding structures may irritate it. That pattern does not prove bursitis, however. Several heel conditions can feel similar, so an examination is important.
Repetitive stress, injury, and footwear
Repeated loading is one possible contributor. Running, jumping, prolonged standing, or a sudden increase in activity may place more stress on the heel than the tissues are ready to handle. A direct impact, ankle injury, or other trauma might also inflame the bursa. MedlinePlus identifies repetitive stress or injury, sports, and improper footwear as potential contributors to heel bursitis. But the presence of one of these factors alone cannot establish the cause of heel pain: heel bursitis information from MedlinePlus.
Shoes may add to the problem when they press against the back of the heel, lack adequate cushioning, or do not support the foot well. A recent change in work shoes, athletic shoes, or daily walking habits can be useful history for a clinician. Footwear is one part of the overall picture, not a standalone diagnosis.
Achilles tightness and foot mechanics
The Achilles tendon and retrocalcaneal bursa share limited space. If the tendon and calf complex are tight, movement may increase compression around the bursa. Abnormal foot posture, overpronation, or flat feet might also change how force travels through the heel and increase stress on nearby structures. Research describes these biomechanical patterns as possible contributors, not certain explanations for every case. A clinician may consider your gait, activity level, flexibility, and shoe wear together rather than focusing on one finding.
Systemic health factors
Some health conditions may increase a person’s risk of bursitis. Mayo Clinic lists systemic conditions such as rheumatoid arthritis and gout among factors that can contribute to bursitis in various joints. These conditions do not mean that heel pain is automatically bursitis, and they may require a different evaluation or treatment approach. If pain follows an injury, persists after an activity or footwear change, or occurs alongside other health concerns, a podiatric assessment in Katy can help clarify what is affecting the heel.
How Is Heel Bursitis Different From Other Heel Pain?
Heel pain can feel similar across several conditions, even when the irritated structure is different. Heel bursitis involves inflammation of a small, fluid-filled sac that cushions moving tissues. In the back of the heel, the retrocalcaneal bursa sits between the Achilles tendon and the heel bone. Plantar fasciitis affects the band of tissue along the bottom of the foot, while Achilles tendinitis affects the tendon itself. These distinctions matter because the right evaluation and treatment plan depend on identifying the structure involved.
| Possible cause | Where symptoms may be felt | Helpful clues |
|---|---|---|
| Heel bursitis | At the back or underside of the heel, depending on the bursa involved | Tenderness, swelling, stiffness, or pain when the area is pressed or the ankle moves |
| Plantar fasciitis | Along the bottom of the heel and foot | Pain follows the plantar fascia rather than the back-of-heel bursa |
| Achilles tendinitis | Along the Achilles tendon, often near the back of the ankle or heel | Tenderness or pain tracks with the tendon and may relate to tendon loading |
| Haglund-related irritation | At the back of the heel where footwear may rub | A bony prominence can irritate nearby soft tissue and contribute to bursal symptoms |
| Possible fracture | Localized heel pain after an injury or repetitive impact | Significant pain, swelling, bruising, or difficulty bearing weight needs prompt assessment |
This table offers general clues, not a way to diagnose yourself. For example, pain at the back of the heel could involve the bursa, Achilles tendon, or irritation related to a prominent heel bone. You can learn more about heel bursitis and Haglund-related irritation without assuming that every back-of-heel bump has the same cause. Likewise, information about heel discomfort related to the Achilles tendon may help explain why tendon pain and bursal pain are evaluated differently.
A foot and ankle specialist may use your symptom history and a physical examination to compare these possibilities. Questions about a recent injury, activity changes, shoe pressure, and the exact location of tenderness can be useful. Imaging may be considered when a fracture or another structural problem needs to be ruled out. If heel pain is severe, swelling is marked, or you cannot bear weight normally, seek medical evaluation promptly rather than relying on symptom comparisons alone.
How Is Heel Bursitis Diagnosed?
There isn’t one test that confirms every case of heel bursitis. A clinician begins by listening to how the pain started, where it is located, and what makes it better or worse. That information helps distinguish irritation of a bursa from other causes of back-of-the-heel or bottom-of-the-foot pain.
Reviewing your history and possible triggers
Expect questions about recent changes in activity, sports participation, walking or running volume, and any injury. Your clinician may also ask whether you recently changed shoes, started wearing a different heel height, or spent more time on hard surfaces. These details matter because repetitive stress, equipment, and activity patterns can help identify factors contributing to heel symptoms. A history of conditions such as gout or rheumatoid arthritis may also be relevant, since systemic health conditions can increase the risk of bursitis.
Examining the heel and ankle
During the physical examination, the clinician may gently press around the heel and assess tenderness, swelling, warmth, and pain with movement. They may evaluate the Achilles tendon, the underside of the heel, the ankle, and nearby joints rather than focusing on one structure in isolation. The exam can also include observing how you stand and walk, checking ankle flexibility, and considering whether foot mechanics are placing additional stress on the area.
This clinical step is important because plantar fasciitis, Achilles tendinitis, nerve irritation, a bony prominence, and a stress fracture can produce overlapping symptoms. Physical examination is the primary tool for evaluating heel pain and helps guide decisions about whether additional testing is appropriate. Clinical research on heel pain evaluation describes this approach and the need to consider different possible sources.
When imaging or gait analysis may help
Imaging isn’t automatically needed for every suspected case. If your findings suggest another problem, an X-ray may help evaluate the bones or rule out a fracture. Other imaging methods may be considered when a clinician needs more information about soft tissues or the bursa. These decisions depend on your history and examination findings, so tests are not guaranteed.
Advanced Ankle & Foot offers in-office digital X-rays and biomechanical gait analysis as part of its diagnostic capabilities in Katy. Gait analysis can provide additional information about how your foot and lower limb move, while digital X-rays can help assess bone-related concerns when indicated. If you have ongoing heel discomfort, a focused evaluation can help determine which next step is appropriate.
What Can Heel Bursitis Treatment in Katy Involve?
Care for heel bursitis usually begins with steps that reduce pressure and irritation around the affected bursa. The right plan depends on the suspected location, symptom severity, activity demands, and what an examination shows. Conservative care is often given time to work before more involved options are considered. The Pain & Injuries care team can help place persistent heel pain in the right clinical context.
- Rest the irritated area. Temporarily reducing activities that reproduce pain can limit repeated compression of the bursa. Rest does not always mean complete inactivity. It may mean pausing running, jumping, uphill walking, or another specific trigger while maintaining comfortable movement as appropriate. Bursitis symptoms can take weeks or longer to settle, so consistency matters. Mayo Clinic describes rest as a common part of bursitis treatment.
- Use ice and modify activity. Ice may help calm discomfort for some people when used safely. Activity modification can also replace high-impact exercise with a lower-impact option, such as cycling or swimming, if that activity is comfortable and medically appropriate. Stop or scale back an activity that increases symptoms rather than trying to push through worsening pain.
- Review shoes and heel pressure. Footwear with suitable cushioning and support may reduce stress on the heel. A clinician may also consider whether a stiff heel counter, worn-out shoe, recent shoe change, or activity-specific footwear is contributing to irritation. The goal is not simply to buy a particular shoe. It is to match footwear changes to the suspected source of pressure and the person’s daily needs.
- Discuss medication safely. Over-the-counter pain relievers, including certain nonsteroidal anti-inflammatory drugs, may be included in a conservative plan for some patients. They are not appropriate for everyone and can interact with health conditions or other medications. Ask a qualified healthcare professional or pharmacist whether an option is medically appropriate for you instead of relying on a general article for personal medication advice.
- Consider physical therapy or guided exercises. Physical therapy may address flexibility, strength, movement patterns, and biomechanics that place extra stress on the heel. Stretching or strengthening should be selected and progressed for the individual, particularly when the Achilles tendon or another nearby structure may also be involved. A personalized plan is more useful than forcing a generic exercise routine through pain.
- Escalate care when symptoms persist. If symptoms do not improve with conservative measures, a podiatric evaluation can help reassess the diagnosis and discuss next options. In selected cases of persistent bursitis, a targeted corticosteroid injection may be considered after other conservative treatments have failed, but it is not appropriate for every heel problem. EPAT is an option at Advanced Ankle & Foot for selected chronic heel-pain conditions, such as some cases involving plantar fasciitis or Achilles-related pain. It should not be presented as a blanket heel-bursitis treatment. Explore the practice’s Treatments & Therapies overview with a clinician to determine whether any treatment fits the findings.

When Should You Seek Evaluation for Heel Bursitis?
Not every episode of heel soreness requires urgent care, but ongoing or worsening pain deserves attention. Heel bursitis can resemble plantar fasciitis, Achilles tendon problems, a stress injury, or irritation related to the shape and mechanics of the heel. A physical examination helps distinguish these possibilities and guides an appropriate plan. Early identification and conservative care may also help keep the problem from becoming chronic.
Seek prompt medical evaluation if heel pain is severe or disabling, especially when it prevents normal walking or makes it difficult to bear weight. You should also be evaluated if you suddenly cannot move the foot or ankle normally, or if symptoms worsen sharply after an injury or change in activity. These patterns do not prove heel bursitis, but they can signal an injury or another condition that should not be assessed solely at home. The Mayo Clinic advises medical evaluation for disabling pain, sudden loss of movement, and significant swelling, redness, bruising, or rash.
Watch for signs of possible infection
Marked swelling, redness, or warmth over the painful area warrants prompt attention, particularly when accompanied by fever or chills. Infection of a bursa is uncommon, but septic bursitis can require immediate medical treatment. Do not wait for symptoms to resolve on their own when heel pain is paired with feeling ill or rapidly increasing warmth and redness. Avoid trying to diagnose an infection based on appearance alone.
Persistent pain also merits an examination
Schedule an evaluation when heel pain continues despite reducing aggravating activity, using comfortable supportive footwear, or following other reasonable self-care measures. Recurring symptoms, pain that repeatedly limits work or exercise, and tenderness that returns whenever normal activity resumes are also reasons to seek guidance. A podiatric evaluation can account for your symptoms, activity history, footwear, and any recent injury. Depending on the findings, imaging may be considered to rule out a fracture or assess nearby soft tissue.
If you are unsure whether your symptoms have reached that point, these guidelines can help you seek evaluation for persistent heel pain. In Katy, an individualized assessment can help clarify whether the bursa is involved and which next step is appropriate.
Frequently Asked Questions
What is heel bursitis?
Heel bursitis is inflammation of a bursa, a small fluid-filled sac that cushions moving tissues. Retrocalcaneal bursitis affects the sac between the Achilles tendon and heel bone, often causing tenderness or pain at the back of the heel. Symptoms can overlap with other conditions, so an examination is needed to identify the source. Learn more about the retrocalcaneal bursa.
How can you tell heel bursitis from plantar fasciitis?
The location and pattern of discomfort may offer clues, but they do not confirm a diagnosis. Bursitis commonly involves the back of the heel, while plantar fasciitis affects the band of tissue along the bottom of the foot. Achilles tendinitis involves the tendon itself. These conditions can feel similar, which is why persistent heel pain deserves clinical evaluation. Review common causes of heel pain.
Can you walk with heel bursitis?
You may be able to walk, but walking through worsening pain can continue to irritate the area. Consider reducing activities that increase symptoms and choosing lower-impact movement while arranging an evaluation. Do not force weight-bearing if pain is severe or you cannot walk normally.
How long does heel bursitis take to improve?
Recovery varies with the cause, severity, and how consistently irritating activities are modified. Rest, ice, footwear changes, and other conservative measures are commonly used, but inflammation may take weeks or longer to settle. If symptoms persist or keep returning, a podiatric evaluation can help guide the next step. See conservative bursitis care guidance.
When is heel pain urgent?
Seek prompt medical attention for severe or disabling pain, inability to bear weight, marked swelling or redness, sudden worsening, or fever, chills, and warmth around the area. These signs can indicate an injury or infection and should not be assessed through self-care alone. Request an appointment in Katy for persistent or concerning symptoms.
Schedule an Evaluation for Persistent Heel Pain
Heel pain that persists or interferes with normal activity deserves an individualized evaluation, especially when the cause is unclear or symptoms are concerning. A podiatric assessment can help distinguish heel bursitis from other conditions and guide an appropriate next step.
