If you need a console command to go to a particular stage, you should be able find it in the Nehrim Wiki
http://nehrim.wikia.com. If you are losing health as you travel, do you lose it in the daylight and dark? I'm just speculating you might have become a vampire, or you might have some ring or shield for night vision that causes damage in the daylight. But you said you took off everything and still had the problem, right? You might try a previous save just to see if that would eliminate the problem, then you would at least know it was something that you did after the last save, and not some freakish code damage. Maybe I don't understand your problem correctly.
Just had one more thought, have you tried Dispel (potion or spell)?
