KO loop due to injury

[Ciego]

Character KO'd by a bat, woke up at homestead stone, 3 to 5 seconds of consciousness until next KO. (Ran to his leafy bed and went to sleep, at the moment)
Is this permanent? Or do injuries heal with time?
This is the second time this has happened to a char - earlier char stepped too close to a coal clamp, and was burned/injured, and after two days, I woke him to check on him during a blood moon, instant perma-death.
There is not a problem with madness or insanity for the moment, and no disease indicator. Just the stars circling his head. Can another alt bring him a "cure" for an injury? Or is this char necessarily going to die?
(Or do I need to do more research, was this covered somewhere?)

This has been covered. He is on your neck in your equipment. You have to quickly ctrl-click him off and run away or kill him. I have no idea what you are referring to with the coal clamp.

First thing. Stars circle every time You are KO'ed. Second use custom client by Latikai (idk if Ender have it) this one got auto drop bat from Your neck. After bat is dropped use Roundhouse Kick to kill it.
Burn from the fire?? Probably Your Tinder Drill broke when You were trying lit a coal clamp.

Thank you both for your replies. Trismegistus, your advice solved my problem. I ctl-E'd on login, and when he woke at the homestead stone, I ctl-clicked on the bat, and immediately stomped once, and dead bat was on ground beside me, stars gone, and char ok now.
A previous character (dead now) was in a mine, first/only level, with a burning coal clamp near a non-burning kiln. I was carrying a mined boulder and moved to pass between the coal clamp and the kiln, and I saw movement at the top of the screen, and my blue bile was dwindling steadily. I then noticed that I was standing just inside the edge of the coal clamp, and I quickly dropped the boulder, but it blocked my exit from the clamp. I clicked the "X" at top-right, panic-exit from game, on the theory that I would not materialize back into the clamp, but rather at my homestead stone. True, but I was constantly KO'ing, like this LATEST character did. Looking back, I wonder if HE had a bat, and NOT a "burn injury".
...Older, but wiser now. Thank you both.

There is no such thing as a burn injury, you kept losing bile due to carrying said boulder, and my guess is that you didnt drop it in time, so KO´d by it reaching 0.
