Why does it sting when antiseptic/antibacterial solutions touch an open flesh wound?

Answer 1

They’re mostly alcohol based (usually isopropyl, not ethanol, so DO NOT DRINK). Isopropyl alcohol literally kills living cells (that’s why we use it as an antimicrobial) when human cells die, their neighboring nerve cells release a signal to the rest of the body, which we call “pain”
