My HP keeps draining, and I die within 10 seconds, anyone have a fix?

Load an earlier save?

Oh! I had this happen to me once... It was after a fight in Corvega, I was wearing PA, couldn't access a terminal for some reason, and no Stimpaks repaired my health. If I remember correctly...I slept for an hour in a bed and it fixed the problem. I believe it is a glitch or bug, really.

Did this by any chance had anything to do with Radiation? I know someone who Dutch who played the game and ran into a bug where he was getting constant radiation damage and there wasn't any fix and diamond city residents starting attacking him out of the blue. His game was clearly super bugged on the ps4 version. He stopped playing until all the patches and stuff was up before starting a new save but it was quite bizarre and humorous imo

There was another case in the bugs section where it turned out a guy was trying to eat food to keep the radiation at bay... Of course all he was doing was adding more radiation and dying.

Sounds like Mirelurk Queen poison to me.

(before you die) Take a buffout followed by a stim.
