Delayed Vasovagal Attack

My wife told me about a small boy who went to her clinic for a booster shot of a vaccine. He was five years old. His mother and grandfather were with him. The grandfather waited in the waiting room, while the mother took the child into the examination area and put him prone on the table. She moved his shorts down and my wife started giving him the injection. He had not been aware till that moment that he was to receive an injection. So when the needle touched him, he screamed, threw himself in the air, and became uncontrollable in general. So the grandfather was summoned, who helped hold him down and then the injection was administered uneventfully. But the child did not forget the insult easily. He continued to bawl. The mother cuddled him, spoke sweetly to him, distracted him by telling him about other things of interest. He would become quiet for a few seconds, and then remember the whole matter and start bawling again. Five minutes passed like this. Then the bag held by the mother slipped from the mother's hand, the bottle of medicine fell on the floor, her eyes rolled up, and she followed the bottle to the floor. The grandfather panicked and requested the doctor to put some medicine in the mother's mouth. The doctor reassured him, put her flat with her head turned to one side, and sprinkled some water on her face. Then the mother gradually came to. A history of fear of dispensaries was obtained retrospectively. One good thing from the mother's vasovagal attack was that the child's bawling stopped instantly, and did not start again even after the mother was revived.
