After the sudden flashes of the atomic explosion in Hiroshima, the narrator of the poem, the doctor received major physical injuries that not only created pain and discomfort, but also made the doctor unable to walk the distance to reach the hospital. We don’t know whether it was a fatal injury or not, whether he finally succumbed to it, but it was severe enough to leave him on the ground.

Add to this the answer of this question: Describe the physical and mental agony of the doctor.
