Noticed this for about 2 weeks. It's not full vertigo as things aren't spinning as such (although I have had this previously), but it's more like, ordinary movements such as changing direction when walking or going from one room to another causes dizziness, as if I'm still "catching up" when changing direction. Also sometimes feel like I'm swaying/in a boat when lying down in bed. Going to the GP tomorrow and will request bloods, etc, but any ideas what it could be? It's really horrible. Google suggests labyrinthitis, but I'm not really nauseous and it wasn't a sudden onset, just something I've noticed.
