My step son fainted in the shower this morning. When I talked to him about what he felt just before , Very light headed and said his vision went from full to a tunneling small circle then he remembers lying on the shower floor with me talking to him through the door asking what just happened.. His response was that he had no idea. After further discussion he reviled that he has had similar episodes at school but has never fainted. His pupils were reactive , and proper sized for the light we were ink at the time. Speech was good after he relaxed for a moment.
