For the past few weeks I have felt really dizzy anytime I lie down, literally the room starts spinning and I feel as if I might pass out. It's ok in bed but if I lie on the floor I have to get up immediately. Today it even did it when I just tilted my head to the side. I have no other symptoms really, I had a virus and a sickness bug a few weeks ago so don't know if it's a hangover from that.
Is this what vertigo feels like? Or does it sound more like a sinus issue? Any input welcome
