After the injury, there is a sudden sensation in the ear, short-term earache, or a small amount of blood flowing out of the external auditory canal, followed by ear nausea, deafness, and tinnitus. In severe cases, there may be dizziness. Symptoms decrease or disappear after hours or days, and a few can have tinnitus affecting work and study. In the case of simple tympanic membrane rupture, the hearing loss is relatively light. If the ear of Inner Mongolia Autonomous Region is damaged at the same time, severe deafness may occur.
