I have some cracked skin on my hands and a few of my fingers are bleeding. I may have accidentally put one of these fingers while asleep (not sure). I know blood (even human) is forbidden to swallow) *If* that did happen, is that something for which I would need to do anything even though out of awareness?
It is not a problem.
All the best
This is a ‘safek ve’aino miskaven’. In addition, the issur to eat one’s own blood is maris ain (Shulchan Aruch Y:D 66:10)
