This seems to be a common thread, my wife's EDS diagnosis took more than a decade. It's a straightforward and obvious physical ailment. Even after her diagnosis she ran into problems - she once had to leave an ER without treatment for an unrelated problem, because the attending refused to treat her until she admitted that she was lying about her diagnosis. Hearing her stories and seeing first-hand how her medical interactions go has really shaken my faith in the medical system.
I've heard that MS was stigmatized like that before the neurology was appreciated. But EDS has one of the highest disability-to-stigma ratios of any disorder I've known. It gave me a spinal cord injury, for Pete's sake.
Ideally the check from a knowledge perspective is CMEs and a separate group of medical researchers that inform med school curriculum, but there is no real check on the eye-rolling and "oh, you have to deal with one of THOSE" that they are exposed to during residency.
If only I could mark myself with “never administer cipro and friends” in some way that would be respected even if unconscious…
I have EDS, and cipro spooked me so I didn't fill my Rx for it in college. If I had I'd likely be even more disabled than I already am.
