Past couple of nights when been laid down if I tilt to my head to left side, the room starts moving & I go very dizzy. It only seams to happen in the middle of the night when I wake up & also if I get up to the loo in the night. I am ok during the day & when up & about but I have a lot facial pain & bad headache. I am sure its just sinus pain but don't really understand why I keep going dizzy in the middle of the night when am laid down. It's not making me panic just yet but worried it will if it carrys on. Do you think its worth going to the docs over? any suggestions to what it might be? x
