Heel spurs are a common source of foot discomfort that affects many individuals worldwide. These bony growths on the underside of the heel bone can cause persistent pain and make everyday activities challenging. While often associated with plantar fasciitis, heel spurs are a distinct condition that requires specific attention and treatment approaches.
This guide aims to provide a comprehensive overview of heel spurs, covering their causes, symptoms, and available treatment options. We’ll explore the various diagnostic methods used to identify heel spurs and discuss both conservative and surgical approaches to managing this condition. By understanding heel spurs better, individuals can take proactive steps to alleviate pain and improve their overall foot health.
What are Heel Spurs?
A heel spur, also known as a bone spur, is a bony growth caused by a calcium deposit that protrudes from the underside of the heel bone. These growths can extend forward by as much as half an inch and are often visible on X-rays. In some cases, the condition may be referred to as “heel spur syndrome” when there is no visible evidence on X-ray.
Definition
Heel spurs are bony protrusions that develop on the underside of the heel bone, where it connects to the plantar fascia, a fibrous band of connective tissue that runs along the bottom of the foot. Although heel spurs themselves are often painless, they can be associated with heel pain and are frequently linked to plantar fasciitis, an inflammation of the plantar fascia.

Causes
Heel spurs typically develop over a period of several months due to repeated stress on the foot muscles, ligaments, and plantar fascia. This stress can cause strains, stretching, and tearing of the membrane covering the heel bone. Athletes who engage in activities involving significant amounts of running and jumping are particularly susceptible to developing heel spurs.
Risk Factors
Several factors can increase the likelihood of developing heel spurs:
- Walking gait abnormalities that place excessive stress on the heel bone, ligaments, and nerves near the heel
- Running or jogging, especially on hard surfaces
- Poorly fitted or worn-out shoes that lack appropriate arch support
- Excess weight and obesity
- Increasing age, which decreases plantar fascia flexibility and thins the heel’s protective fat pad
- Diabetes
- Spending most of the day on one’s feet
- Frequent short bursts of physical activity
- Having either flat feet or high arches
While heel spurs can be removed surgically, healthcare providers typically recommend non-surgical treatments to manage the symptoms associated with this condition.
Symptoms of Heel Spurs
Heel spurs often cause no symptoms. However, they can be associated with intermittent or chronic pain, especially while walking, jogging, or running, if inflammation develops at the point of the spur formation. In general, the cause of the pain is not the heel spur itself but the soft-tissue injury associated with it.
Many people describe the pain of heel spurs and plantar fasciitis as a knife or pin sticking into the bottom of their feet when they first stand up in the morning or after a long period of sitting. The pain often decreases the more they walk, but it may return after prolonged rest or extensive walking.
Common Signs
The most common symptoms of heel spurs include:
- Pain on the bottom of the foot near the heel
- Pain with the first few steps after getting out of bed in the morning or after a long period of rest, such as after a long car ride; the pain subsides after a few minutes of walking
- Greater pain after (not during) exercise or activity
- Inflammation and swelling at the front of the heel
Differentiating from Other Foot Conditions
To determine if heel spurs are causing the pain, doctors will typically examine the foot, looking for points of maximum tenderness, and may use imaging tests to rule out other conditions. Heel spurs can be seen on X-rays, but they are not always the cause of pain. Many people have heel spurs without experiencing any pain or discomfort.
Other conditions that cause similar heel pain include plantar fasciitis, insertional Achilles tendinitis, calcaneal stress fractures, and plantar nerve entrapment. A thorough examination and imaging tests can help differentiate between these conditions and guide appropriate treatment.
Diagnosis Methods
Diagnosing heel spurs involves a combination of physical examination and imaging tests to identify the presence of a bony outgrowth on the heel bone. The process also includes ruling out other potential causes of heel pain to ensure an accurate diagnosis.
During the physical examination, the healthcare provider will carefully examine the foot, looking for points of maximum tenderness. They may also assess the range of motion in the ankle and foot, particularly the passive dorsiflexion of the toes. Palpation of the proximal plantar fascia attachment at the heel can reveal the presence of a calcaneal spur, tenderness, or deformities.
Imaging tests play a crucial role in confirming the diagnosis of heel spurs. X-rays are the most common diagnostic tool used to visualize the bony outgrowth on the heel bone. They provide clear images of the bones and can help rule out other causes of heel pain, such as fractures or arthritis. Heel spurs are often visible on X-rays as a pointed or shelf-like projection extending from the heel bone.

In some cases, additional imaging tests may be ordered to further evaluate the condition or rule out other potential causes of heel pain. An MRI scan may be used if the heel pain does not respond to initial treatment methods or if the healthcare provider suspects a different underlying problem. MRI scans provide detailed images of the soft tissues and can help identify any abnormalities in the plantar fascia or surrounding structures.
To ensure an accurate diagnosis, healthcare providers must also consider and rule out other conditions that can cause similar symptoms to heel spurs. These may include plantar fasciitis, Achilles tendinitis, calcaneal stress fractures, and nerve entrapment syndromes such as tarsal tunnel syndrome. A thorough examination and appropriate imaging tests can help differentiate between these conditions and guide appropriate treatment.
Treatment Options
There are several treatment options available for managing heel spurs, ranging from conservative approaches to surgical interventions. In most cases, healthcare providers recommend starting with non-surgical treatments to alleviate pain and improve mobility.
Conservative Treatments
Conservative treatment options for heel spurs include:
- Stretching exercises to help relax the plantar fascia and reduce strain on the heel
- Wearing supportive shoes with good arch support and shock absorption
- Using custom-made orthotics or shoe inserts to redistribute pressure and provide cushioning
- Applying ice packs to the affected area to reduce inflammation and pain
- Taking over-the-counter anti-inflammatory medications such as ibuprofen or naproxen to manage pain and inflammation
- Receiving cortisone injections to provide temporary relief from severe pain and inflammation
- Wearing night splints to gently stretch the plantar fascia and calf muscles during sleep
- Participating in physical therapy to improve flexibility, strength, and overall foot function
More than 90% of people with heel spurs experience improvement with these non-surgical treatments. It is important to give these conservative measures sufficient time, typically several months, to determine their effectiveness before considering surgical options.

Surgical Interventions
If conservative treatments fail to provide relief after a period of 9 to 12 months, surgery may be necessary to address chronic pain and restore mobility. Surgical options for heel spurs include:
- Plantar fascia release: This procedure involves partially cutting the plantar fascia ligament to relieve tension and reduce inflammation.
- Removal of the heel spur: In some cases, the bony outgrowth itself may be removed to alleviate pain.
Pre-surgical tests and exams are required to identify optimal candidates for surgery. Following the procedure, patients must adhere to post-surgical recommendations, which may include rest, icing, compression, elevation of the foot, and a gradual return to weight-bearing activities. Some patients may need to use bandages, splints, casts, surgical shoes, crutches, or canes during the recovery process.
As with any surgery, there are potential risks and complications associated with heel spur procedures. These may include nerve pain, recurrent heel pain, permanent numbness in the area, infection, and scarring. Additionally, plantar fascia release carries the risk of foot instability, cramps, stress fractures, and tendinitis.
Conclusion
Heel spurs can have a significant impact on daily life, causing discomfort and limiting mobility. This guide has shed light on the causes, symptoms, and various treatment options available to manage this condition. From conservative approaches like stretching exercises and orthotics to surgical interventions in severe cases, there are numerous ways to address heel spur pain and improve foot health.
Understanding heel spurs is key to taking the right steps to alleviate pain and prevent future issues. By seeking proper diagnosis and following recommended treatments, most people can find relief and return to their normal activities. Remember, patience is crucial when dealing with heel spurs, as conservative treatments often need time to show results. If you’re struggling with persistent heel pain, don’t hesitate to consult a healthcare professional to explore the best options for your specific situation.
