I have had an arrow dead center in my forehead for oh about 5 days now (GT) and it never seems to go away... it will fade instead of clipping if i zoom in... but never leaves its faithful faceperch.

will the Dr. not pull it for fear of bleeding?

I haven't had the problem with arrows yet, but I did have an ice shard stuck in my shoulder after fighting a mage. Regardless, I took all the arrows that were in my inventory and put them in a container and closed it (I was in a first-person view at the time; I'm not sure if that matters). After doing that I switched to a third-person view and the ice shard was gone. Then I retrieved my arrows from the container and saved the game. See if that works for you.

Getting hit by the same projectile removes the one that's stuck on you.

Or type sixchange twice in the console.

When you have an arrow stuck in your head just go to the inventory and you should see it there. Just unequip and that's it. It works for me always.

Are you on a console or the PC?

If PC use the console and enter 'sixchange' to change your body to female/male then re-enter it to return to normal.

That should solved it for me.

If Console i'm afraid i can't help

Thanks guys and gals (if any) i will give it a shot when i get home and see if i cant remove the pesky penetration.

Change into a werewolf and then wait till you'll change back then it should be gone.
