I went to the emergency room of Crema for heart attack symptoms.
at first glance, everything seemed to be going well and after 3.5 hours under observation, the employees tell me that the tests performed were fine (samples, x-ray and cardiological examination).
They make me sit in the waiting room, which the doctor would have called me to discharge shortly thereafter
In front of me there are about ten patients and at that moment the doctor is called for an emergency ........ when would he have discharged me?
In summary, I arrived at the P.S. at 17.30 and 22.30 I went home without the doctor's discharge.
It is not possible that in a PS there is only one doctor for these practices
little more than bureaucratic
Shame!!!!!!
