Heel pain can be classified based on its location and cause:

1. Plantar heel pain: Pain on the underside of the heel, usually associated with the plantar fascia.
2. Dorsal heel pain: Pain on the back of the heel, often in the area of the Achilles tendon.
3. Medial or lateral heel pain: Pain on the inner or outer side of the heel, often caused by nerve or soft tissue changes.

The main causes of heel pain are diverse and include:

• Plantar fasciitis:
  • One of the most common causes of heel pain, where the plantar fascia is inflamed. This often occurs due to overuse, prolonged standing, or intense running.
• Heel spur:
  • A bony growth on the heel bone caused by repeated tension on the plantar fascia, which can lead to pain.
• Achillodynia:
  • Pain in the area of the Achilles tendon, often caused by overuse, degenerative changes, or inflammation.
• Bursitis:
  • Inflammation of a bursa near the heel bone, often due to pressure or overuse.
• Stress fractures:
  • Small cracks in the heel bone that occur due to repeated stress, such as in runners or hikers.
• Nerve compression:
  • In tarsal tunnel syndrome, the posterior tibial nerve is compressed, which can lead to sharp pain or tingling in the heel.
• Systemic diseases:
  • Diseases such as rheumatoid arthritis, gout, or diabetes mellitus can trigger secondary heel pain. 

The symptoms vary depending on the cause, but often include:

- **Pain when walking or standing:**

- Often sharp or burning, especially after long periods of rest or in the morning.

- **Local swelling:**

- Often accompanied by redness and warmth in the affected area.

- **Tenderness:**

- Pain that increases with pressure on the heel, especially in plantar fasciitis or heel spurs.

- **Movement restrictions:**

- Difficulty with normal walking or rolling of the foot.

- **Radiating pain:**

- Occasionally, the pain extends into the foot or ankle.

The diagnosis is made through a combination of medical history, clinical examination, and imaging techniques:

- **Medical History:**

- The doctor inquires about the course of the pain, possible triggers, and existing preconditions.

- **Physical Examination:**

- Palpation of the heel, assessment of mobility and pain sensitivity.

- **Imaging Techniques:**

- **X-ray:** Visualization of bony changes, such as a heel spur or a stress fracture.

- **MRI:** Detailed visualization of soft tissues and inflammatory processes, as in plantar fasciitis.

- **Ultrasound:** For the assessment of bursae or the Achilles tendon.

Conservative Therapy

Most heel pain can be treated with conservative measures:

• Immobilization and Load Reduction:
  • Avoidance of intense activities and resting the heel.
• Physiotherapy:
  • Exercises for stretching and strengthening the plantar fascia and Achilles tendon.
  • Manual therapy to relieve tension.
• Pain Medication:
  • Taking anti-inflammatory medications like ibuprofen to relieve acute symptoms.
• Orthopedic Aids:
  • Use of shoe inserts or heel cushions to relieve the affected area.
• Local Applications:
  • Cooling to reduce swelling or heat applications to promote circulation.

Surgical Therapy

Surgery is only considered in severe or chronic cases:

• Fasciotomy: Surgical cutting of the plantar fascia to relieve pressure.
• Removal of a Heel Spur: In cases of persistent pain despite conservative measures.
• Repair of the Achilles Tendon: In cases of tears or severe degenerative changes.

To prevent heel pain, the following measures are recommended:

1. Appropriate footwear: Use shoes with good cushioning and a stable sole.
2. Regular exercise: Strengthen the foot muscles through targeted exercises.
3. Stretching exercises: Regularly stretch the plantar fascia and calf muscles, especially for physically active individuals.
4. Avoid overloading: Limit intense physical activities and gradually increase training intensity.
5. Weight management: Reduce excess weight to relieve the feet.
6. Early treatment: Immediate clarification at the first signs of pain or discomfort.
