Burning foot syndrome is a painful condition marked by burning, tingling, and aching in the feet, historically observed in prisoners of war suffering severe protein and B-vitamin deficiency. It reflects damage to peripheral nerves from prolonged malnutrition, similar to the neuropathy seen in thiamine and other B-vitamin deficiencies. Symptoms worsen with heat and at night, and walking can become difficult. Treatment centres on restoring adequate nutrition, particularly protein and the B-complex vitamins, alongside foot care. The syndrome is now rare where diets are adequate but remains a textbook example of how micronutrient deficiency manifests in the nervous system.
