Anecdotally this rings very true. Actually I'd be even more cynical than it. I know two people that were facing serious chronic health issues that were not readily diagnosed. They were treated like a hot potato between specialists. In one case it took nearly 2 year to arrive at a correct diagnosis and corrective action, which involved both medication and surgery. In the other case the person was moving into liver failure, and placed on the transplant list. Luckily a family friend worked for the same healthcare organization as an IT professional, and knew exactly what to do. She marched the patient into the ER, had her sit down in a wheel chair, and made it crystal clear that she was going to be a gigantic PITA until they found out what was killing the patient. Within the day they had a plausible answer, and confirmed it with lab results within the week as I recall. It shouldn't be this way, but unfortunately in US healthcare it is. Having an uncommon illness is an absolute nightmare, one that destroys entire families finances if not outright killing people.
