Heel pain is a common issue that brings many people into the podiatrist’s office. In most cases, it’s caused by something manageable like plantar fasciitis, nerve compression, or tendon inflammation. But when pain becomes persistent or doesn't improve with rest, it's normal to feel concerned, especially if the symptoms seem unusual or more severe than what’s expected.
This may lead some people to question whether their pain could be linked to something more serious, like a tumor or cancerous growth. While heel pain is rarely a symptom of cancer, it’s worth understanding the signs that may indicate when a deeper evaluation is needed.
Causes of Heel Pain
Most cases of heel pain are due to mechanical or inflammatory conditions. These often develop from overuse, poor or improper footwear, or standing for prolonged periods. The most common causes of heel pain are:
- Plantar fasciitis, caused by microtears and inflammation in the plantar fascia—a thick band of tissue that runs along the bottom of the foot
- Achilles tendonitis, which affects the tendon at the back of the heel
- Stress fracture, a fatigue or weakness in the heel bone caused by overuse
- Apophysitis (Sever’s), inflammation of the heel bone growth plate in adolescence
- Retrocalcaneal Bursitis, which involves inflammation of the fluid-filled sac near the Achilles tendon
- Tarsal tunnel syndrome, compression or impingement of a nerve that can cause burning pain or tingling in the heel
These conditions typically respond well to rest, stretching, supportive footwear, and orthotics. However, when pain persists despite these efforts, further evaluation is recommended.
Could Heel Pain Ever Be Cancer?
In very rare cases, heel pain may be caused by a tumor in the bone or soft tissue of the foot. Some cancers, such as osteosarcoma (a type of bone cancer), Ewing sarcoma, or metastatic cancer (cancer that has spread from another part of the body), may cause localized pain.
Here are a few warning signs that could indicate a more serious issue:
- Pain that worsens at night or when you're at rest
- Swelling or a noticeable mass around the heel
- Persistent or increasing pain despite rest or conservative care
- Unexplained weight loss or fatigue
- Unusual changes in skin texture, color, or temperature near the site of pain
If you notice any of these symptoms, it’s important to speak with a healthcare provider.
How Is Heel Pain Diagnosed?
When you visit a podiatrist or primary care provider, they’ll begin by reviewing your medical history and symptoms. From there, they may:
- Perform a physical exam
- Order imaging tests like an X-ray, MRI, or CT scan
- Conduct bloodwork or a biopsy, if a tumor is suspected
What Should You Do If Heel Pain Doesn’t Go Away?
When heel pain does not improve, it can begin to affect posture, gait, and overall mobility. It may also lead to compensatory biomechanical changes, resulting in pain in the knees, hips, or lower back.
In some cases, heel pain may be a more serious condition, such as a stress fracture, nerve entrapment, or, in rare instances, a tumor.
Most heel pain isn’t serious, and it often gets better with time and care. But if yours isn’t improving, it could be a sign that something else is going on. Foot and ankle specialists at CLS Health are here to help you figure out what’s behind the discomfort and how to treat it effectively.
