What does airplane pressure do to your body?

During ascent and descent, as the cabin pressure changes, gas trapped in the body and sinuses react in turn. Typical problems, as a result, include earaches from the pressure difference on either side of the eardrum, headaches from expanding air inside the nasal sinuses, and the need to pass gas that swell in the gut.
