An injury caused by expansion or contraction of trapped gases in the body resulting from changes in pressure. It can lead to pain in the ears (otitic barotrauma), the sinuses (sinus baro-trauma), and the intestines.
One example of barotruauma is otitic barotrauma. During ascent, higher pressure in the ear gets equalized. However, during descent, the air from outside is not able to equalize unless there is some action like chewing, swallowing, and valsava maneuver. The situation gets aggravated in case of sinus congestion in which there may not only be pain in the ears during descent but physical injury to the ears.
