Overview
A heel spur is a bony outgrowth from the heel bone, also called the calcaneus. Most heel spurs form on the bottom of the heel near the plantar fascia attachment, although spurs can also develop on the back of the heel near the Achilles tendon.
Heel spurs usually develop gradually. They are often linked to long-term stress where soft tissues pull on the bone, repeated pressure under the heel, inflammation around the plantar fascia, abnormal foot mechanics, tight calf muscles, poor shoe support, high-impact activity, or prolonged standing.
The key point for patients is this: a heel spur on X-ray does not automatically mean the spur is causing the pain. Many people have heel spurs with no symptoms. When pain is present, the surrounding soft tissues, plantar fascia, heel fat pad, nerves, bursa, or tendon attachments may be the real source of discomfort.
Heel Spurs vs. Plantar Fasciitis
Heel spurs and plantar fasciitis are related, but they are not the same problem. Plantar fasciitis is irritation of the thick band of tissue that runs from the heel to the ball of the foot. A heel spur is extra bone that can form where that tissue attaches to the heel.
Plantar fasciitis often causes sharp, stabbing pain with the first steps in the morning or after sitting. The pain may ease after walking for a short time and return after long standing or activity. Heel spurs can be present in patients with plantar fasciitis, but the spur is often more of a sign of chronic stress than the direct cause of every painful step.
This distinction matters because simply “removing the spur” is rarely the first answer. Treatment usually focuses on reducing plantar fascia strain, improving shoe support, cushioning the heel, stretching tight tissues, correcting pressure patterns, and calming inflammation.
What Causes Heel Spurs?
Heel spurs develop when the body responds to repeated stress by laying down extra bone. The process is usually slow and reflects chronic traction, compression, inflammation, or overload rather than a single sudden injury.
Common contributors
- Plantar fasciitis or repeated pulling at the plantar fascia attachment
- Long periods of standing or walking on hard surfaces
- Running, jumping, or high-impact activity
- Tight calf muscles or limited ankle flexibility
- Flat feet, high arches, abnormal gait, or uneven pressure patterns
- Worn-out shoes, unsupportive footwear, or lack of heel cushioning
- Increased body weight or sudden activity changes that increase heel load
- Age-related loss of soft-tissue flexibility and heel fat-pad cushioning
- Repetitive micro-tearing or irritation of tissue around the heel bone
Heel pain should not be guessed at from an X-ray alone. Schedule an appointment to find out whether the spur, plantar fascia, pressure pattern, nerve, tendon, or another heel problem is driving the pain.

Symptoms And Warning Signs
Some heel spurs cause no symptoms at all. Others are associated with pain because nearby tissues are inflamed, irritated, compressed, or overloaded.
Possible symptoms
- Sharp or stabbing pain under the heel
- Aching, bruised, sore, or tender feeling at the bottom of the heel
- Pain with first steps in the morning or after rest
- Pain that worsens after standing, walking, running, or hard-surface activity
- Tenderness where the plantar fascia attaches to the heel
- Inflammation, warmth, or swelling around the heel in some cases
- Pain that improves briefly with movement but returns later in the day
- Discomfort that changes gait or causes limping
Red flags
Seek care promptly for severe pain after injury, inability to bear weight, spreading redness, fever, open wounds, numbness, black skin, sudden swelling, or heel pain in a patient with diabetes, poor circulation, or immune compromise.
Risk Factors
Heel spurs are more likely when heel tissues are exposed to repeated stress over time. Some risk factors can be changed, while others are part of foot structure, aging, or work demands.
- Plantar fasciitis or chronic heel inflammation
- Occupations requiring long standing or walking
- Running, jumping sports, dance, or sudden training increases
- Hard walking or running surfaces
- Flat feet, high arches, overpronation, or abnormal gait
- Older age and reduced plantar fascia flexibility
- Loss of natural heel fat-pad cushioning
- Unsupportive shoes, worn athletic shoes, or walking barefoot on hard floors
- Excess body weight or sudden weight gain
- Tight Achilles tendon or calf muscle tightness
How Heel Spurs Are Diagnosed
A podiatry evaluation starts by identifying the actual source of heel pain. The exam considers symptom timing, activity level, footwear, work demands, running or walking patterns, medical history, and the exact area of tenderness.
Physical exam
- Checking the bottom and back of the heel for tenderness
- Testing plantar fascia tension and calf/Achilles tightness
- Looking for swelling, nerve symptoms, bruising, wounds, or skin changes
- Evaluating arch type, gait, shoe wear, and pressure distribution
- Checking for related problems such as plantar fasciitis, stress fracture, bursitis, tendonitis, arthritis, or nerve irritation
Imaging
X-rays can confirm whether a heel spur is present and help rule out fracture, arthritis, or other bone problems. Ultrasound, MRI, or other imaging may be considered if symptoms suggest plantar fascia tearing, soft-tissue injury, stress fracture, nerve entrapment, or another diagnosis that an X-ray cannot fully explain.
What Not To Do
Heel pain often gets worse when patients keep pushing through it or chase the wrong explanation. A spur on an X-ray is useful information, but it does not replace a full heel pain diagnosis.
- Do not assume the spur itself is the only cause of pain
- Do not continue running or high-impact activity through worsening heel pain
- Do not rely only on thin sandals, worn-out shoes, or barefoot walking on hard floors
- Do not ignore heel pain that changes your gait or causes limping
- Do not use aggressive home treatments that irritate the skin or cause burns
- Do not delay evaluation if you have diabetes, poor circulation, numbness, wounds, fever, or significant swelling
Most heel spur pain starts with conservative care. A focused exam can match treatment to the real cause instead of treating every heel spur the same way.

Treatment Options
Most heel spur cases are treated without surgery. Treatment focuses on reducing pain, calming inflammation, unloading the heel, stretching tight tissues, improving mechanics, and addressing plantar fasciitis or other underlying conditions.
Rest and activity changes
Reducing running, jumping, prolonged standing, or hard-surface activity can give irritated heel tissues time to calm down. Activity is usually modified rather than stopped forever.
Ice and anti-inflammatory care
Ice can reduce soreness after activity. Anti-inflammatory medication may be appropriate for some patients, but it should be used safely and with attention to medical history, allergies, kidney disease, blood thinners, stomach problems, and other medications.
Stretching and physical therapy
Calf stretching, plantar fascia stretching, foot strengthening, night splints, manual therapy, and gradual loading programs may reduce strain at the heel. Physical therapy can help patients with tight calf mechanics, weak foot muscles, gait issues, or persistent plantar fascia pain.
Supportive shoes, heel cups, and orthotics
Supportive shoes, cushioned heel cups, arch support, shoe inserts, and custom orthotics can reduce pressure under the heel and improve how force moves through the foot. Orthotics are especially useful when flat feet, high arches, pronation, or abnormal gait mechanics contribute to the problem.
Injections and advanced nonsurgical care
When pain persists, a podiatrist may discuss corticosteroid injections or other targeted treatments depending on the diagnosis. Injection decisions depend on the tissue involved, symptom severity, medical history, and risk profile.
Surgery
Surgery is rarely the first treatment for heel spurs. It may be considered when months of conservative care fail and symptoms remain severe. Procedures may address the plantar fascia, remove a spur, release tight tissue, or correct another structural problem. Surgery carries risks and recovery time, so it is reserved for carefully selected cases.
Recovery And Long-Term Outlook
Most patients improve with nonsurgical care, but recovery can take weeks to months depending on how long the pain has been present, how much stress the heel is under, and whether plantar fasciitis or another condition is involved.
The spur itself may remain visible on X-ray even after pain improves. That does not mean treatment failed. The goal is to reduce pain, restore walking comfort, improve function, and control the soft-tissue stress that made the heel painful.
Symptoms are more likely to return if patients go back to worn shoes, hard-surface overuse, sudden training increases, poor support, untreated tightness, or the same pressure patterns that caused the flare.
Prevention And Flare Reduction
Not every heel spur can be prevented, but heel pain flares can often be reduced by lowering repeated stress on the heel and plantar fascia.
- Wear supportive shoes with cushioning and arch support
- Replace worn athletic shoes before support breaks down
- Avoid prolonged barefoot walking on hard floors
- Stretch the calves and plantar fascia consistently
- Increase walking, running, or standing demands gradually
- Choose softer training surfaces when possible
- Use heel cups, inserts, or custom orthotics when pressure patterns require support
- Manage weight-related heel load when appropriate
- Treat heel pain early instead of waiting for limping or chronic inflammation
