my 6yr old son has high temps, loss of appitite and a bad cough, mainly at night and quite dry, also been feeling very sick and is sleeping alot. i ve taken him to the Dr s, he said his ear drum was slightly red and believes thats the problem and perscribed antibiotics 4 days ago. how ever, symtoms remain the same, except, his cough is worsening. should i take him back and get a second opinion?
