When children say their ears hurt, the usual causes are acute otitis externa, herpetic tympanitis, acute suppurative otitis media and so on. 1. Acute otitis externa: usually due to the child’s ear into the water, excessive digging in the ear and other reasons, resulting in local skin damage to the external auditory canal, by the bacterial infection, resulting in acute otitis externa. Due to the thin skin of the external auditory canal and the abundance of local nerve endings, the pain will be more obvious when inflammatory lesions occur. 2. herpetic tympanitis: because this disease often occurs in viral acute upper respiratory tract infections during the epidemic, may be caused by viral infections, earache often occurs suddenly, and rapidly aggravated, this deep ear pain for the distension or tingling sensation, persistent, generally very intense, can be accompanied by headache and cheek pain on the same side. After the rupture of the blister, the ear pain can be gradually reduced. 3. Acute suppurative otitis media: due to the child’s Eustachian tube structure is more flat than adults, respiratory tract infection, inflammation can be retrograde along the Eustachian tube and caused by the disease, which leads to acute tympanic membrane congestion, so that the tympanic membrane of the tension becomes larger, while purulent secretions stimulate the nerve inside the drum, can cause ear pain. If the child’s ear pain symptoms, it is recommended to send to the regular hospital in a timely manner, a clear diagnosis and targeted treatment.
