When a child has tonsillitis, symptoms may include a sore throat, fever, cough, lethargy, and headache.

The child is 10 months and 1 week old. This morning, the child started crying and vomiting, with the vomit being sticky and sour, containing milk residue. The parent described the child as possibly having caught a cold or indigestion. The doctor suggests undergoing a routine blood test and an emergency department ultrasound, and paying attention to staying warm and diet. At the same time, one can try drinking small amounts of ginger-sugar syrup several times to alleviate symptoms.
