Now that is something I’ve never thought about before and also wish I hadn’t read.

Anyway, I googled it, and hemorrhoids are actually not necessarily open wounds, and if they are, at least the blood is flowing outwards which might hinder the bacteria from getting into the blood stream. The bacteria from the asshole doesn’t survive well outside the intestines, so there’s a low risk of them crawling back up into an open wound.

However it does happen, and that could cause blood poisoning, which is potentially lethal if untreated. You’d probably want to treat it though because you’d experience severe fever and other clear signs.

I’ll achieve this knowledge in the “don’t worry about it” folder.
