Children catching a cold indicates that they have an acute upper respiratory tract infection, which is mostly caused by viral infections, while others are caused by bacteria or mycoplasma infections. If a child experiences ear pain after catching a cold, we must be highly vigilant about whether the cold has caused otitis media. It is essential to take the child to an otolaryngology clinic promptly, allowing the doctor to examine the painful ear with an otoscope. If it is confirmed that the child has otitis media, treatment should be administered based on the type of otitis media, such as serous otitis media or bacterial otitis media. With active treatment, the problem of ear pain can be quickly alleviated and cured.
