Sounds like the Martian booggie poops to me!
With the Shakey shivers thrown in with it!
Seriously your balance problems could be that your nasal and sinus congestion is also affecting your inner ear! You can always try eating chicken noodle soup and get plenty of rest! See a Doctor when you can. or go to a convenient care clinic either one would be the best thing to do!
Good Luck to You!
