Is a Sore Heel After Running a Cause for Concern?

Heel soreness is common among runners and is not always a cause for concern. It can happen when the heel has been placed under more stress than usual, and mild soreness often settles with rest.

If the soreness becomes painful and begins to affect running or walking, there may be an underlying problem that needs attention.

What You Should Know About Heel Soreness After Running

• Mild heel soreness after running often settles with rest.
• Soreness that becomes painful, persists or affects walking may indicate an underlying problem.
• The location of heel pain can help distinguish between Achilles tendinopathy, plantar fasciitis and stress injuries.
• Persistent or worsening heel pain should be examined to determine the cause and appropriate treatment.

Common Causes of Heel Pain

Achilles tendinopathy, plantar fasciitis and stress injuries are among the possible causes of heel pain after running. Each condition tends to affect a different area of the heel and produce a different pattern of pain.

Achilles Tendinitis or Tendinopathy

Achilles tendon pain is usually felt at the back of the heel or slightly higher along the tendon. The area may feel tender after running, with stiffness after rest or during the first few steps in the morning.

Pain where the Achilles tendon attaches to the heel is known as insertional Achilles pain. Pain slightly higher along the tendon is commonly associated with Achilles tendinitis or tendinopathy.

Plantar Fasciitis

Plantar fasciitis usually causes pain underneath the heel rather than at the back. The pain is often noticeable with the first few steps after getting out of bed or after sitting for some time.

Although plantar fasciitis and Achilles problems can both cause discomfort after rest, the location of the pain is usually different.

Stress Injury

Repeated stress from running can sometimes cause a stress reaction or stress fracture in the heel bone. The pain tends to increase with weight-bearing activity and may gradually begin to affect walking.

Unlike ordinary post-run soreness, pain from a stress injury may become progressively worse if running continues.

Why Can Running Make Your Heel Sore?

Running repeatedly loads the heel, Achilles tendon and surrounding structures. Soreness can develop when these tissues are placed under more stress than they are used to.

This commonly happens when running distance or frequency is increased too quickly. Faster running, hill training or returning to your previous training level after a break can also place additional stress on the heel.

Footwear may contribute, particularly if the shoes are worn out or place pressure on the back of the heel. Calf tightness and the way the foot moves during running may also contribute to symptoms.

When Should You Consult a Doctor for Heel Pain?

Heel pain should be checked if it:

• Does not improve with rest
• Keeps returning when you run
• Becomes progressively worse
• Starts to affect walking or weight bearing
• Is accompanied by persistent swelling or weakness

Sudden heel pain during running or sport needs more immediate attention. A sudden pain or pop at the back of the ankle followed by weakness may indicate an Achilles tendon rupture. You may also have difficulty pushing off the affected foot or standing on tiptoe.

If this happens, seek immediate medical attention.

Treatment for Heel Pain

Treatment depends on what is causing the heel pain and how severe the symptoms are. The location and pattern of the pain, together with a physical examination, usually help determine the likely cause. Imaging such as an X-ray, ultrasound or MRI may be needed in some cases.

For running-related overuse problems, treatment often begins with reducing activities that aggravate the pain. This may mean cutting back on running for a period rather than continuing through the symptoms.

Achilles tendinopathy commonly involves progressive calf and tendon strengthening, while plantar heel pain may require exercises targeting the foot and calf. Physiotherapy may also be recommended as part of recovery.

A stress injury requires greater protection from weight-bearing exercise while the bone heals. An Achilles tendon tear requires different treatment depending on the extent of the injury.

Returning to Running After Heel Pain

Once the heel pain has improved and everyday walking is comfortable, you can gradually return to running. The timing will depend on the cause of the pain and how well the heel has recovered.

Start with shorter, easier runs before gradually increasing the distance. Faster running and hills can be introduced later as the heel becomes more comfortable with regular running.

Pay attention to how the heel responds during and after each run. If the pain returns or increases, reduce your running and allow more time for recovery.

Frequently Asked Questions

Can I continue running if my heel hurts?

You may continue running if the soreness is mild and settles quickly. Stop if the pain worsens or affects your walking or running.

Why does my heel hurt when I first get out of bed?

Heel pain during the first few steps in the morning is commonly associated with plantar fasciitis. Achilles tendinopathy can also cause morning stiffness, usually at the back of the heel or along the tendon.

How long should heel soreness last after running?

Mild heel soreness usually improves within a day or two with rest. If the pain lasts longer or worsens, consider seeing a doctor.

Why does my heel pain go away and then come back?

Heel pain may return when you resume or increase running before the affected area has fully recovered. Conditions such as Achilles tendinopathy or plantar fasciitis can also cause symptoms to come and go.

When a Sore Heel Needs Attention

If symptoms continue despite rest or reducing your running, an orthopaedic specialist can evaluate the heel and advise on appropriate treatment and a safe return to running.
