> We briefly discussed my anxiety, but his immediate solution was the anti-anxiety drug. I made it clear that I was worried about the procedure and wanted to know more details about it. He didn’t want to explain the procedure beyond “we’ll inject medication that will help preserve your vision”, and he avoided answering repeated questions. Maybe he tried to shield me from the details and not confirm my worst fears.
Based on stories I've heard from emotionally immature doctor friends and my own experience being a little more confrontational with my doctors, he most likely didn't know the answers to your questions and was too proud to say, "I don't know."
It seems many forget that, at the end of the day, doctors are people, too, with just as many flaws and emotions as the rest of us. It's unfortunate that this affects quality of care, but it's a fact of life in every industry.
The best thing you can do for yourself in such a situation is to prepare yourself before appointments and remember the humanity of doctors during appointments. If your doctor is being dodgy about answering questions, let them know that it's okay if they don't know and that you won't think anything less of them for it. If it's an urgent matter, suggest looking it up together so that your doctor can provide context for whatever research you manage to find.
A doctor is like a contractor you've hired to inspect and maintain your body. As with any contractor, if you want them to do a good job, you have to work with them, as a team.
