I had that happen to me, too.
Found in my player file that I had contracted parasites.
There seem to be some undocumented / unfinished status effects in the game.

They don’t show up in the status screen and their effects are extremly frustrating/ debilitating.
Proably should be removed until they are actually finished.
Editing your playerfile and removing those effects fixed my character.
