My 6 year old takes eight days followed by coughing , coughing so hard that you vomit , have a headache , sore throat , neck hurts , no fever , is very pale , has the white cloudy eyes and not eat.
Cough with vomiting always makes me think of pertussis, but does not describe a dry cough before vomiting. Something more serious, however, are the 8 days of not eating and dull pallor associated sclera. Take your child to the doctor today, or else the hospital.
