my son was really unwell over the weekend - high temperature (102.7), coughing so much he was sick. he cried so much it was obvious he was in agony and when i fed him he would wince in pain. i thought he might have tonsilitis but i have noticed he has white spots on his tongue. are they mouth ulcers (in which case i can understand why he was screaming when i gave him food)or is it a symptom of another more serious illness? he has a couple of red spots on his face too.
