One very common cause of ear pressure is changes in barometric pressure. When people change altitude quickly, problems can occur in the Eustachian tubes and the ear can feel blocked. Many people have this sensation when they're on airplanes, and some will even feel it if they quickly climb a mountain in a vehicle.
Ears popping due to change in altitude are the result of the pressure difference between the inside of our heads and the surrounding air. Pressure decreases with altitude, due to the reduction of the mass of overlying air with height. Pressure is c. 700 mbar at 3,000m; 500 mbar at 5,500m; 300 mbar at 10,000m.
