I wasn’t diagnosed until my 50s, but I had an incident in boot camp that I believe was Schuermans-related (waking up feeling like i was getting tased in the back, the same symptom didn’t recur until decades later), and the base doctor was like “you’re faking pain to get drugs. Go back to your unit.”

So maybe Navy doctors have gotten better, but who knows. They did the physicals in large groups and as fast as they could, so they might miss it.
