They do. In my experience they're usually pleasantly surprised when you have dates and timelines rather than "oh I don't know, about a year ago?"
That being said the reaction differs if you offer a self diagnosis (assisted by google or chatgpt) rather than just symptoms. There will not be pleasantness. It's a toss up between a dismissive "yeah maybe" and "uh uh, did google tell you this?" Many doctors will 100% listen and consider what you say, but in my long life I've learned that offering a self diagnosis must be done very tactfully.
On one hand it's understandable, us as programmers don't enjoy having a nocoder arrive with "yeah so chatgpt says this is no good" and having to explain to them why they're wrong. On the other hand modern patients do their own research before consulting, so it's worth at least considering what's being said.
