my son suddenly got hot i mean severely hot out of no where a few hours ago and i took his temp and it was 104.2 a few hours later and it is being controlled with tylenol and motrin but i he is refusing liquids and he is shaking and literally seconds after giving him his second dose of motrin about 5 mins ago he projectiled vomited like the exorsist type puking everywhere. im really sad and idk what to do, i dont know if i should take him to the ER bc id have to take an ambulance out there and then id be stuck out there or if i should wait it out. also what could this be?
