Medical professionals: What’s something the general public should know, but they usually don’t?

Aspirin is the devil’s right hand. It’s a pretty shitty solution to pain, and if it’d be put on the market today, it’d be prescription only and exclusively for cases where its anti-platelet function is needed and not an unwanted side-effect.
No, antibiotics are not the cure-all for your winter flu. Since most things you catch around this time are viral, you will do nothing to the illness and contribute heavily to this shitty world in which most of them don’t work well anymore, thanks to resistances. We live in the beginning of an antibiotics-resistance-pandemic, that will kill more and more people. Anyone who pops antibiotics when they didn’t need to and anyone who stops sooner than being told, contributes to statistically more deaths than HIV.
ER are for life threatening illnesses, not to get a day off work or to get your prescription refilled. They’re also a bad place to get a second opinion if your doctor said someting you disagreed with. And, most importantly, they’re not a first-come-first-serve place. Attention is based on your likelihood of dying. Yes, your pain is important, but it is the third factor in a list of things that rank you, following your risk of dying and the public’s risk of exposure to lethal illnesses.
And, yes, that means if you can come on Quora and complain about the ER not doing their job, it did its job. Its job is to make sure you can leave and complain. If you don’t leave the ER, then we fucked up.
There are (at the shortest way) 249 steps between food arriving in your stomach and it becoming energy your muscles or brain can use. Your heart uses different fuels than your brain, your muscles another set, and so on. Don’t let anyone, not the “medical doctors” on this site, nor a book, nor YouTube, nor a listicle telling you that “doctors say,” tell you what’s right. Because there is no such thing as a “right” way, and neither eating meat nor sugar nor fructose, nor flour, nor beeswax will kill you or make you inherently unhealthy. Understand, that even “Doctors” can’t tell you this stuff, only on person can: YOUR physician, after reading YOUR data, speaking with YOU, and consulting experts about YOU.

don’t?
