My 23 mo old boy has had an ear infection for a week and was prescribed augmentin. he was doing better but now his congestion is way worse, green mucus in nose and chest. today he broke out in a rapid spreading rash. it started on his buttocks and inner thighs, now it is on his legs , soles of his feet (which he is itching at crazily) and on his left arm. i soaked him in an oatmeal bath and covered him in hydrocortizone cream and gave him some benedryl. also there are about 5 bumps that look like pimples spread throughout the rash, 2 on buttocks, 2 on each leg, and one on his big toe.
any help diagnosing this ?
should i bring him to ER? ashlynn..
