Differential Diagnosis for Heel Pain

The following is a comprehensive differential diagnosis for heel pain, categorized for clarity and emphasis on potential severity.

• Single Most Likely Diagnosis

  • Plantar Fasciitis: This is the most common cause of heel pain, resulting from inflammation of the plantar fascia, a band of tissue that runs along the bottom of the foot. It is often associated with overuse, poor foot mechanics, or inadequate footwear.

• Other Likely Diagnoses

  • Achilles Tendinitis: Inflammation of the Achilles tendon, which connects the calf muscles to the heel bone. It's common in runners and athletes who participate in sports that involve running or jumping.
  • Heel Spurs: Bony growths on the underside of the heel bone, which can cause pain when walking or standing. They are often associated with plantar fasciitis.
  • Bursitis: Inflammation of the fluid-filled sacs (bursae) that cushion bones, tendons, and muscles near the heel, often due to repetitive motion or pressure.
  • Stress Fractures: Small cracks in the heel bone, typically caused by overuse or repetitive stress, common in athletes.

• Do Not Miss Diagnoses

  • Infections (e.g., Osteomyelitis, Septic Arthritis): Although less common, infections in the heel area can be serious and require prompt antibiotic treatment. Signs of infection include redness, warmth, swelling, and fever.
  • Tumors (e.g., Bone Cysts, Soft Tissue Tumors): Both benign and malignant tumors can occur in the heel, causing pain. Early detection is crucial for effective treatment.
  • Rheumatologic Conditions (e.g., Rheumatoid Arthritis, Gout): Systemic diseases that can affect the heel, among other joints, and require specific management to control symptoms and prevent long-term damage.

• Rare Diagnoses

  • Tarsal Tunnel Syndrome: A condition that is similar to carpal tunnel syndrome but affects the nerves in the heel, causing pain, numbness, and tingling.
  • Fat Pad Atrophy: A condition where the fat pad under the heel becomes thinner, leading to pain and discomfort, often seen in older adults or those with certain systemic diseases.
  • Entrapment Neuropathies: Compression of nerves around the heel, which can cause pain, numbness, and weakness in the foot.

Each of these diagnoses has distinct clinical features and may require specific diagnostic tests for confirmation. A thorough medical history, physical examination, and sometimes imaging studies are essential for an accurate diagnosis and appropriate treatment plan.
