The question you left without asking
It is almost never the big question. It is the small one, the slightly embarrassing one. Whether it will show. Whether you should have come a year ago. Whether the thing you have been doing at home has made it worse. Those questions need a language you are relaxed in, and if you are not relaxed they simply do not get asked. You leave, and they stay with you.
The same is true of describing pain. Sharp or dull, on biting or on cold, at night or after coffee. In a second language most people give up early, say it hurts, point roughly, and stop. Those distinctions are half of a diagnosis, and they are exactly the half that goes missing.
