Being received in the emergency room for a respiratory problem and coming out with 2 unconvincing diagnoses (asthma attack or viral pneumonia) so I can go home without worry without medication but he made me sign a document for my blood sample that will serve test for pulmonary embolism.The next day I went to the emergency rooms of clinics in Europe where they diagnosed bacterial pneumonia so treatment with antibiotic (penicillin) .If I did not bother to return to emergency I went home with confidence to die.
I really wonder about university hospitals.
