From time to time, I am asked to review and make a plan for a patient I have not clerked in myself. So that the description of their symptoms is second hand via verbal handover, or written notes. When I make the plan to send home, I always summarise an overview of the situation and ask the parent if they are happy and have any questions.
And on a few occasions, usually when I'm under a lot of time pressure and have been rushing, it turns out that are very not happy and that this is because I have made a complete mistake or omission in my understanding of the history of the symptoms.
In this instance, I feel grateful to the parent for speaking up because they have potentially saved us both a deal of trouble. Good doctors, I believe, want to enable their patients to speak up and correct them where they have misunderstood or just plain got something wrong. Patients (or in my case parents of patients) are oftentimes the best safety net a doctor could ask for.
If you are concerned, frightened, not reassured, think the doctor is or even may be mistaken in something, you should not keep it to yourself. You are helping your doctor (and yourself or course) by speaking up. Good doctors will see it this way. Rather than you being embarrassed, they probably feel embarrassed by the misunderstanding.
And btw, bursting into tears is nothing to be ashamed of - we've evolved crying for a reason, because it effectively communicates our feelings & evokes an emotional response even to/in strangers, and often to our advantage. That has clearly been the case here. Those tears did their job!
Hope you are feeling better soon.
