you left out a very important fact: the age of your son. if a child was under three to six months old we take any fever quite serious but if the child is older fever rarely gets the attention of a seasoned medical provider. why? because fever is not dangerous even in the 105 range. it is the body's normal response to fighting off an illness (in kids this is usually a virus). you do not have to rush him to the hospital with a temperature of 102. 3 unless you enjoy sitting for hours in a crowded er while other patients go in front of him. you are not unusual in your fear of fever. fever is one of the most normal yet least understood symptoms. relax. fever is higher in the evening; lower in the morning so it always goes up and down. whether you try to reduce it with acetaminophen or ibuprofen will not really help the illness but it will make him feel better. even though fever is not dangerous it does make a child feel yucky so it is okay to treat for comfort. the real issue is not the fever but the cause of the fever. your son should be examined to see if a biological cause can be determined. you can take him to an urgent care facility or just call his pediatrician for patient-specific advice. not knowing your son's age this answer is the best i can do for you.
