My father was having fever around a week back. he went to doctor and he had prescribed zerodol and antibiotic. He takes nebicard sm daily. His fever was 102 a day before. During night he was going to throw saliva he fainted and was unconscious. he was fainted for 3-4 minutes. His eyes were open. On hitting hard he came back to senses. He had stool in his pants. we went to doctor a day after. Ecg reports were normal. Can it be attack? i am worried. what should i do. he has no chest pain or anything.
