What does mean saying "the nail was lodged in between his toes"? This ia the whole passage. Conversely, a man in Britain jumped off scaffolding and impaled his foot on a large nail. His pain was immediate and severe enough that it required intravenous sedation and pain medication. However, when his boot was removed, the nail was lodged in between his toes and had not injured him. (Reference: Minerva. British Medical Journal. 1995, 310: 70.) His pain was caused by the brain activating a powerful danger/alarm signal. Thank you
