Boy do I know this well. During the high pollen season around here I have caught myself walking down hallways and literally slam into a wall from being off balance. Almost like being a cheap drunk What is really weird is you don't know you have an inner ear problem, since at the start of it there is no pain. Mine normally comes right after my sinus cavities get really stuffy, I can breath fine, but the cavities are swollen, thereby pushing down on the inner ear tube. (At least that is how my Doctor explained it) If I don't get it taken care of, then it turns into a painful ear infection.

Whatever you do, do not try to work out with an inner ear problem. You only run the risk of injuring yourself or someone near by.

Hope you feel better soon!
