My son had a bout of diaherra and vomiting a couple of weeks ago. Since then every few days he gets stomach cramps, diaherra and some vomiting. Between these episodes he's up running about and not generally unwell. I've been trying to get an appointment with the GP but seem to be getting no where. I've started keeping a food diary. Thinking of cutting out diary and seeing how he gets on or should I keep pushing and get him a GP appointment before I do anything?
