I held in a sneeze and as soon as i got up the whole room started spinning. it has lasted 10 min probably more.i am leaning to one side with ear pain?

Oooo... sounds bad: Humans are probably the only mammals who try to hold a sneeze. What happens to all that high air pressure? Where does it all go? Aside from trying to win at hide-n-seek, and a few other situations, it's not natural nor wise to contain that explosive sneeze. The pressure likely got into the ear's hearing and balance system... meaning a call to the ENT doctor if symptoms don't vanish later today.
