to make an analogy to physical health:

someone has chronic gastrointestinal pain, but they just live with it and have never talked to a doctor about it.

they watch a video from someone talking about having chronic GI pain and getting diagnosed with ulcerative colitis.

they go to a doctor and say "I think I have ulcerative colitis"

the doctor runs tests, and they come back negative.

I get that it's tempting to say "oh this person was misled by a video on social media"

but, the pain they were feeling was real. even if they jumped to an incorrect conclusion about its cause.

and after those negative tests, they can work with their doctor to find out "ok, what else might be causing my symptoms?"
