To be honest, many doctors dump patients that need "too much" care. It may not happen among the specialists who expect to spend a certain amount of time per patient with complex issues, but in my experience, it happens all the time with PCP's who said they are open to taking on new patients but that doesn't mean (in their minds) the patient that is in pain that needs being treated now, and 3 or 4 referrals, along with their Current Medications list being updated lots, and their Adverse Reactions List being full of past drugs already known to not be compatible. The more complex your case is, the less likely you are to find competent Primary Care, which is the backbone of getting good specialists. I've had Resident Doctors (I, in fact, have one now) graduate and move on out of town, and I've been gaslit in years prior by incompetent PCP's I should have had the sense to leave right away. Those things complicate one's medical care too. Not to be a "debby-downer" but when/if it seems the doctor and you are not communicating well, find another. Especially, if you are being harmed. There's good ones out there, sometimes we have to wade through the mud to find one. Healthcare systems with good reputations is likely half the battle and maybe even more than that. There's a reason Mayo is so well respected all around the whole world.
