[Bug] Any tips on getting rid of the red glow clouding my vision?

I've gone back to playing my first character ever since Dawnguard came out on PC and (I believe) after my first werewolf transformation to check out the perk tree, I've gotten stuck with a [red glow around my head](http://cloud-2.steampowered.com/ugc/578964108928195665/A1606E2C93877573327EF5F8A228C648C99134B5/) that I think first appeared while I was devouring corpses but never went away after I changed back to human form.

I've made sure it's not associated with any gear, I've rested since then (on top of playing for 10 more hours with a [red glow engulfing my screen most of the time](http://cloud-2.steampowered.com/ugc/578964108929915749/7AD6CFB043483DF267690174281FB9DCDC5758A9/)), I've cured my lycanthropy, I've checked my mods, I've tried changing my face... Nothing has made it go away and it's really getting on my nerves. I've searched the internet but couldn't find anyone with a similar problem or any solutions. Anyone have any clues on anything I could try to get rid of my crimson halo?
