Heel pain is a frequently encountered complaint in clinical settings, with a multitude of potential underlying causes. While numerous factors can contribute to heel discomfort, mechanical issues are often the primary culprits. Precisely identifying the location of the pain is crucial in guiding clinicians toward an accurate diagnosis. Plantar fasciitis stands out as the most prevalent cause of medial plantar heel pain, characterized by exacerbated pain during the initial weight-bearing steps after periods of rest, such as upon waking in the morning. However, medial heel pain can stem from a range of other conditions that necessitate careful differentiation.
Understanding the differential diagnosis of medial heel pain is essential for effective patient management. Beyond plantar fasciitis, several other conditions can manifest with pain in the medial aspect of the heel. Calcaneal stress fractures should be considered, particularly in individuals who have recently increased their activity levels or transitioned to harder walking surfaces; this typically presents as progressively worsening pain. Nerve entrapment syndromes may also cause medial heel pain, often accompanied by sensations of burning, tingling, or numbness radiating into the heel and potentially the sole of the foot. Heel pad syndrome, characterized by a deep, bruise-like pain in the central heel, can sometimes extend to the medial aspect. Furthermore, although less common in the medial heel specifically, neuromas and plantar warts remain possibilities in the broader context of plantar heel pain and should be considered in a comprehensive differential diagnosis. Tarsal tunnel syndrome, involving compression of the posterior tibial nerve, is a significant cause of medial midfoot and potentially heel pain, especially with continued weight-bearing activities.

Differentiating between these potential causes of medial heel pain requires a systematic approach. A thorough patient history is paramount, focusing on the onset, duration, location, and characteristics of the pain, as well as any aggravating or relieving factors. Physical examination plays a crucial role, involving palpation of the medial heel structures, assessment of range of motion, and specific provocative tests to reproduce symptoms and identify the source of pain. For instance, the windlass test can help diagnose plantar fasciitis, while Tinel’s sign might be used to assess for tarsal tunnel syndrome.
In cases where the diagnosis remains uncertain after clinical evaluation, or when red flags such as fracture or nerve entrapment are suspected, imaging studies may be warranted. Radiographs can help rule out calcaneal stress fractures or other bony abnormalities. Magnetic resonance imaging (MRI) can provide detailed visualization of soft tissues, aiding in the diagnosis of nerve entrapments, plantar fasciitis severity, heel pad syndrome, and other soft tissue pathologies. Nerve conduction studies might be considered if nerve entrapment is strongly suspected to confirm the diagnosis and localize the site of compression.

In conclusion, medial heel pain presents a diagnostic challenge due to its diverse etiology. A comprehensive approach encompassing a detailed patient history, meticulous physical examination, and selective use of imaging studies is essential to accurately differentiate between plantar fasciitis, calcaneal stress fractures, nerve entrapments like tarsal tunnel syndrome, heel pad syndrome, and other less common causes. Accurate differential diagnosis is the cornerstone of effective management and targeted treatment strategies for patients presenting with medial heel pain.
