Inability to hear sound in the left ear may be related to ear inflammation, blockage of the external ear canal, trauma and other reasons.
1. Ear inflammation: such as otitis externa, otitis media, etc. Due to the stimulating effect of inflammation, it can cause increased secretion in the ear, which can reduce the hearing in the left ear.
2. External auditory canal obstruction: such as cerumen embolism, foreign bodies in the external auditory canal, etc., which can affect the transmission of sound, and the phenomenon of not being able to hear sound in the left ear.
3. Trauma: If the left ear is hit and other trauma, it can cause ear damage, earache, hearing loss and other symptoms.
It is recommended to go to the hospital in time to clarify the cause of the disease and carry out standardized treatment under the guidance of the doctor, so as not to delay the condition.
