In my experience, doctors don’t treat my health problems seriously regardless of whether they know about my psychiatric issues or not (I don’t have an officially diagnosed PTSD, but I’m diagnosed with OCD and bipolar). It’s just easier for them to find an excuse for not doing their job properly if I tell them I’m mentally ill. But even in cases where they can’t easily brush it off as psychosomatic, they are rarely willing to provide proper diagnostics and treatment. For example, I found out I have a hearing loss in one ear about 6 months ago, and nobody made any effort whatsoever to find the cause up to this date. That is outside of the basic physical examination, which revealed nothing. The first doctor just gave me random medication for vertigo which I don’t even have (they never asked me about it), and the second doctor I’ve tried hasn't really done anything at all. I think the main issue is that most doctors are simply bad and unwilling and/or too incompetent to help. They wouldn’t help even if they didn't know about any mental health issues. They would just find different excuses or, in some cases, wouldn’t even bother to explain why they are doing nothing. In my opinion, if they dismiss someone’s symptoms as PTSD without excluding all the other options first, it already shows they don’t really feel like doing their job. Because ruling out all physical diseases before claiming “psychosomatic” should be a standard procedure, not an extra. I might be biased, though. Part of my trauma is related to doctors/hospitals, so I don't trust doctors at all, and I get into a fight response whenever I see or even think about one. Sorry for the rant.
