I picked up a cold / cough a couple of weeks ago, and all the coughing, sore throat etc is over. But the last week or so I've had a really weird feeling in my head - kind of a dizzy pressured feeling although I'm not actually dizzy. I do suffer with vertigo but it doesn't feel like that. It feels like there's some kind of pressure inside my head that is causing an actual physical kind of pressured spinny, whooshing, heartbeaty kind of feeling in the middle of my head (like if my head was a ball it would be the absolute centre of the ball), and it's making me feel really disoriented and a bit off balance. My ears are fine, I'm not snotty, don't have a blocked nose. I've had a bit of a weird headache on and off on the top of my head but not too painful.
Could it be sinuses? Or a hangover of the cold? Not felt like this before it's really odd!
