So I had the same issue and I backed up my files, and removed Immersive first person, which didn't help. However, I loaded up another character, and he didn't have the issue. When I loaded up my other character, the issue was fixed. Something note worthy about the character that had the issue was that I used this save: http://www.nexusmods.com/skyrim/mods/14263/? to make this character. Hope my way works for you.
