A couple of thoughts. There's good, bad and indifferent online. And IRL. There's difference of opinion. Neither are worthy of unwavering allegiance.

A big thing to keep in mind is how things are presented can make a big difference in how they are received. It's important not to come off like you think they don't know their own job. And that you do. No one likes that, no matter what their job.

Maybe you have read about something. Go ahead and say what it is. If they have a different opinion, ask why. Listen to them. For real. Because they are right? No. Because you want them to listen to you, and they're not going to be inclined to do that if you're not extending them the same courtesy. Also, like it or not, they do have experience that you don't.

You're aiming for a partnership, yes? And what that wouldn't look like would be you telling them what you think you have, what tests they should run and how they should treat it. It isn't a restaurant.

I don't know for sure this is the dynamic, but the two examples you gave make me wonder. Like "about got into it" and the other a situation where you have a symptom, which you have "pre-dx'd" for them as to cause and what test they should run and who and what they should read to educate themselves so that they can know as much as you.

I like Naynay's idea of printing out a bit from reputable sources. Don't go overboard though.

I'm not saying any if this to be harsh. Whoever is "right", I don't really care and won't presume to take a side. My angle/point is that it sounds like you *might* be hurting your own cause unwittingly. Might be a matter of tweaking communication techniques a bit in order to feel more heard. (And remember! Hearing doesn't mean agreeing. If someone doesn't agree, it doesn't mean they don't hear you.)

Good luck! Here's hoping for truly working together for your best health.
