My ds had a tummy bug last sunday/monday with vomiting and diarrhoea. Since tuesady night after he has been to sleep for approx 4 hours he coughs slightly then vomits everywhere. This just happens the once then he goes straight back to sleep.He has an ENT appointment in 4 weeks time due to abnormally large tonsils and is always ill with throat/chest infections, do you think this is related or do we need ( yet another ) gp appointment?
