My 5yo son has had stomach issues for about a year but seems worse recently. He complains after he eats, also says some thing taste bitter. He still eats quite a lot but will occasionally have a kind of flare up where he doesn’t want to eat. Maybe once a month. He sometimes has diarrhoea too.
Hes going to have bloods done but he did have them a year ago go and came back clear.
should I get an at home allergy test?
thanks
