Thanks, fixed.
Umm, that seems to be an issue with the readings. Most times where this passage appears we see lohitapitta, for which I follow Ven Bodhi in rendering as “hemorrhage”. TBH, I don’t really know what it means, and most of these are educated guesses.
Yes, it’s a good point. I’m not really sure, but certainly that would be a reasonable choice. Perhaps it deserves more close research.
