I have just found this site and wondered if anybody has some advice. My little girl has chronic cystitis (? spelling)a few hours after having oranges, orange juice (including cordial)etc. She doesn't have any other reaction ie rash etc but her bits below hurt enough to wake her up crying and it is agony when she goes to the loo. Has anybody known this before and if so do you have any tips besides calpol and sudocreme?
