Sitting in high speed train, the ear is like blocked, which may be caused by the change of air pressure, or it can be the symptomatic manifestation of some diseases, such as tympanic membrane invagination.
1. In healthy people, when taking high-speed railroad, due to the imbalance of air pressure inside and outside the carriages when the high-speed railroad is traveling fast, which leads to the imbalance of air pressure inside the ear, the ear appears to be like blocked, and the symptoms of ear discomfort can be relieved after doing swallowing or pinching the nose to puff up the air.
2. Tympanic membrane invagination, one end of which is normally connected to nasopharynx and the other end is connected to the middle ear, when taking high-speed railroad, the speed is faster and the difference in air pressure may cause the tympanic membrane activity obstacle and tympanic membrane invagination, which manifests the blockage of the ear, and pinching and puffing can not be relieved usually.
Therefore, after excluding physiological factors, it is recommended to consult a regular hospital for further treatment after a clear diagnosis of ear discomfort.
