If you experience sudden pain in your ear, it is possible that you have an acute otitis media condition. The inflammation of the middle ear is often caused by a cold or an acute respiratory tract infection. The eardrum of the patient often shows acute congestion and swelling, and the ear pain is often severe. Some patients may suffer from acute inflammation of the external ear canal due to excessive digging or water ingress in the ear, which may cause acute congestion and swelling of the ear canal and may even have a significant impact on hearing. Some patients may experience neuralgia in the ear, which is a paroxysmal pain in the ear. This is often related to the patient’s emotional state of excessive stress and anxiety, or recent lack of sleep, repeated fatigue, or staying up late.
