Hello, dc (9), has recurring crops of mouth ulcers - in the past these came with fevers. He's had several tests for these - nutritional deficiencies, gastro, coeliac, crohn's etc. We saw leading gastro people who have been clear this isn't a stomach issue. He had low iron but responded to prescription iron and recent re-test shows it's stayed within normal range.
Second week back at school and he's had vomiting, a fever with mouth ulcers and sore throat again with very stinky breath and flatulence. He didn't have a runny nose or cough. It lasted 3 days then he was back to normal self. I've had a theory that it is something that happens to him when he is having a growth spurt since I've noticed it coincides with a change in height.
Does anyone's kids get mouth ulcers when they have an infection? I know that being 'run down' is listed as a reason for mouth ulcers but dc gets a lot of sleep and doesn't have any notable stress!
