Patients with fever over 38℃, if it lasts for about 2-3 days, then it may lead to a series of problems in the patient’s ears, because the inflammation is more serious and may involve the middle ear cavity of the patient, resulting in inflammatory exudate, leading to stuffiness and pain in the patient’s ears or even accompanied by hearing loss, perforation of the eardrum, and flowing water. It is recommended that when a patient develops a fever, he or she must actively monitor the body temperature and actively treat the fever by using some physical methods, such as repeatedly wiping the patient’s palms, feet, and forehead with a warm towel, or using an ice pack to apply cold compresses to the patient’s neck bilaterally. If the body temperature exceeds 39°C, consider taking oral ibuprofen suspension for antipyretic treatment to avoid serious inflammation and uncontrolled involvement of the patient’s ears.
