You're being very defensive as if the person who started their comment with "fun fact" had instead started it with "you're an idiot doing wrong things" - nobody was criticising you, nor claiming they knew your frequency of use. They were sharing useful information on a public forum that, if not useful to you, would still be useful to other people who read your first comment.
Excedrin is a stack of acetaminophen, aspirin, and caffeine, I’ve even been prescribed different combinations a few times, and I’ve had more than one doctor tell me how to rotate painkillers to safely maximize the effect and tell me to drink an energy drink with painkillers to make them work better.
I think it’s that doctors are honestly just excited to tell you the fun trivia.
When I am in pain I want it to go away. This is what I found works best over the years. Last time I used it getting Covid vaccine after effects fever. So awhile ago.
