I am an Internist/Infectious Diseases specialist.
You (and your regular doctor) are right on all counts.
From a social standpoint, it is the duty of the professional staff to act in a neutral and unprovocative way: the patient, who has an illness and may have consequent anxiety, does not need to be assaulted with a staff member’s sociopolitical views.
We are there to help the ill, not to make a statement.
From a medical standpoint, they are guilty of following a protocol instead of taking a careful history, doing a careful physical examination, and ordering appropriate testing to confirm or rule out potential causes of your presenting symptom complex.
If you ask the right questions and then listen to the patient’s answer, they invariably tell you what the diagnosis is.
One of my Rules of Medicine for medical students and trainees is: “When all else fails, speak with and examine the patient”
I trust that you have recovered.
