Heel pain

Heel pain is discomfort felt beneath, behind, around, or deep inside the heel. It may appear suddenly after an injury, develop gradually after repeated strain, or be most noticeable during the first steps after getting out of bed. Some people describe a sharp or stabbing pain, while others feel burning, pressure, tenderness, stiffness, or a deep ache that worsens with standing and walking.

The location and pattern of heel pain provide important clues, but they do not establish a diagnosis on their own. Pain under the heel is often connected with the plantar fascia or the cushioning tissue beneath the heel bone. Pain at the back of the heel may involve the Achilles tendon, a nearby bursa, or irritation from footwear. Deep, persistent, or injury-related pain may require evaluation for bone, joint, nerve, or inflammatory causes.

How heel pain can feel

Pain underneath the heel

Pain beneath the heel may be sharp when the foot first touches the floor after sleep or a period of rest. It may ease after several minutes of movement and then return after prolonged standing, walking, or exercise. This pattern is frequently associated with irritation or degeneration of the plantar fascia, although other structures can produce similar symptoms.

A bruised or pressure-like sensation in the center of the heel may be related to the heel fat pad, which normally cushions the heel bone. Pain from the fat pad is often more noticeable when walking barefoot or standing on hard surfaces.

Pain behind the heel

Pain at the back of the heel may occur where the Achilles tendon attaches to the heel bone. It can be accompanied by stiffness, local thickening, tenderness, or discomfort when climbing stairs, running, or rising onto the toes. Irritation of a small fluid-filled sac near the tendon, known as a bursa, can also cause swelling and sensitivity to shoes.

A prominent area of bone at the back of the heel, sometimes called a Haglund deformity, may rub against footwear and contribute to tendon or bursa irritation. The presence of a bony prominence does not automatically explain all symptoms, so the surrounding soft tissues also need to be assessed.

Deep, side, or widespread heel pain

Deep pain inside the heel may occur after a sudden increase in running, jumping, walking, or load-bearing activity. A stress reaction or stress fracture of the heel bone is one possible cause, particularly when pain becomes progressively worse and weight-bearing is difficult.

Burning, tingling, electric sensations, or numbness may indicate irritation or compression of a nerve. Pain may occasionally be referred from the ankle, lower leg, or lower back rather than starting in the heel itself.

Common causes of heel pain

Plantar fascia and heel pad causes

Plantar fasciopathy, often called plantar fasciitis, is one of the most common causes of pain under the heel. The plantar fascia is a strong band of connective tissue that supports the arch and helps transfer load during walking. Repeated strain, changes in activity, limited calf flexibility, foot mechanics, unsuitable footwear, and prolonged standing may contribute to symptoms.

Heel fat pad irritation or thinning can create central heel pain that feels like walking on a bruise. This pattern may become more noticeable with age, repeated impact, hard surfaces, or reduced cushioning from footwear.

Achilles tendon, bursa, and bone-related causes

Achilles tendinopathy can affect the tendon itself or the area where it attaches to the heel bone. Symptoms may develop after repeated loading, a sudden change in training, reduced tendon capacity, or long periods of inactivity followed by intense exercise.

Bursitis may cause localized swelling, warmth, and tenderness near the back of the heel. Bone-related causes include a stress injury, fracture, arthritis, or structural changes around the heel. A heel spur may be visible on an X-ray, but it can also be present in people without pain and should not automatically be considered the cause.

Injury, overuse, and growth-related causes

A direct impact, fall, awkward landing, or sports injury may affect the heel bone, Achilles tendon, ligaments, or surrounding soft tissues. A sudden pop followed by pain, swelling, weakness, or difficulty standing on the toes may indicate a significant Achilles tendon injury.

In physically active children and adolescents, heel pain may be connected with irritation of the growth plate at the back of the heel, often called Sever disease. It commonly appears during growth periods and may worsen with running or jumping. Persistent heel pain in a child should be assessed rather than assumed to be ordinary growing pain.

Less common inflammatory, neurological, or infectious causes

Inflammatory arthritis, gout, nerve compression, certain systemic conditions, and, less commonly, infection can also cause heel pain. These possibilities become more relevant when pain affects both feet, occurs at rest, is accompanied by prolonged morning stiffness, or appears with swelling in other joints, skin changes, fever, or general illness.

Symptoms that may appear with heel pain

Heel pain may occur together with:

• stiffness after rest or in the morning
• swelling, warmth, redness, or visible thickening
• pain extending into the arch, ankle, or calf
• reduced ankle movement or difficulty pushing off the foot
• limping or inability to bear full weight
• tingling, burning, numbness, or weakness
• a lump or bony prominence at the back of the heel
• bruising after an injury

The combination of symptoms can change the diagnostic direction. For example, first-step pain under the heel suggests a different pattern from sudden posterior pain after a jump, burning pain with numbness, or deep pain that becomes progressively worse during weight-bearing.

When heel pain needs prompt medical attention

Medical assessment should not be delayed when heel pain follows a significant injury, is severe, or makes it impossible to walk normally. Urgent evaluation may be appropriate if:

• there was a snap, pop, or tearing sensation during the injury
• the foot or ankle appears deformed
• you cannot bear weight, climb stairs, or rise onto your toes
• rapid swelling, extensive bruising, or severe calf pain develops
• the heel is hot, red, markedly swollen, or associated with fever
• there is an open wound, drainage, or a rapidly worsening skin change
• numbness, weakness, or loss of normal foot control appears
• pain repeatedly wakes you at night or remains severe at rest

People with diabetes, impaired circulation, reduced sensation, or a weakened immune system should seek medical advice earlier, particularly when heel pain occurs with a wound, redness, swelling, or skin breakdown.

How heel pain is usually diagnosed

Medical history and physical examination

The assessment usually begins with the exact location of the pain, how it started, when it is strongest, and what activities make it better or worse. The doctor may ask about recent changes in exercise, footwear, work demands, previous injuries, medical conditions, medications, and whether the pain affects one or both heels.

During the examination, the clinician may assess walking pattern, foot alignment, ankle movement, calf flexibility, plantar fascia tenderness, Achilles tendon continuity, swelling, nerve symptoms, and the ability to stand or rise onto the toes. The examination helps determine whether the likely source is soft tissue, bone, joint, nerve, or another area.

Imaging and additional tests

Imaging is not required for every case of heel pain. An X-ray may be considered after trauma, when a fracture or important bone change is suspected, or when symptoms persist despite initial care. Ultrasound can help evaluate the plantar fascia, Achilles tendon, bursae, and certain soft-tissue changes.

MRI may be useful when symptoms are unexplained, severe, persistent, or when a stress injury, tendon tear, bone marrow change, or another soft-tissue problem needs closer assessment. Laboratory testing may be considered when infection, gout, inflammatory arthritis, or a systemic condition is suspected.

What the next step may involve

Conservative treatment and rehabilitation

Treatment depends on the cause, duration, activity level, and examination findings. For many non-urgent mechanical causes, the pathway may include temporary activity modification, footwear adjustment, heel cushioning or orthotic support, and a structured exercise or physical therapy program.

Rehabilitation may focus on calf and plantar fascia flexibility, gradual strengthening of the foot and lower leg, movement control, and a progressive return to walking, work, or sport. The load should be adjusted to the individual problem rather than applying the same exercise plan to every type of heel pain.

Additional procedures or surgical assessment

Persistent symptoms may require reassessment of the diagnosis and contributing factors. Depending on the confirmed cause, additional options can include immobilization, targeted physical therapy, shockwave therapy, an image-guided procedure, or another specialist-led treatment.

Surgery is not the usual first step for heel pain. It may be discussed when a clearly identified structural problem, significant tendon injury, fracture, nerve compression, or long-lasting condition has not responded to appropriate non-surgical care.

How the patient pathway may differ

Recent mild pain after an increase in activity may initially be monitored with reduced loading and supportive footwear. Pain that repeatedly returns, lasts for several weeks, alters walking, or limits work and exercise usually warrants a clinical evaluation.

Sudden pain after injury may require earlier imaging and orthopedic or foot and ankle assessment. Posterior heel pain may lead toward Achilles tendon evaluation, while pain beneath the heel may first require assessment of the plantar fascia, fat pad, foot mechanics, and calf flexibility. Burning or numbness may change the pathway toward neurological assessment.

For children, athletes, people with inflammatory conditions, and patients with diabetes or impaired circulation, the threshold for medical evaluation may be lower because the likely causes and associated risks differ.

What to prepare before a medical appointment

Before requesting an appointment, note when the pain began, its exact location, whether it is constant or intermittent, and whether it is strongest during the first steps, after exercise, or at rest. Record any swelling, bruising, numbness, stiffness, injury, fever, or difficulty bearing weight.

It is also helpful to provide information about recent activity changes, sports, work demands, footwear, previous foot or ankle problems, current medications, and treatments already tried. Bring any previous X-rays, ultrasound or MRI reports, discharge letters, and specialist findings.

If heel pain is persistent, worsening, or interfering with walking and daily activities, you can send ZagrebMed a short description of the symptoms and any existing medical records. ZagrebMed can help identify whether an orthopedic consultation, diagnostic imaging, physical therapy assessment, or another appropriate pathway in Zagreb should be considered.
