I would like to rack someone's brains about a bizarre food allergy. I am very sensitive in my um my when I eat certain foods. Give me 30 minutes after eating and I get severe cramping followed by diarrhoea. I know for sure that parmesan cheese does it to me along with avos and some sauces. I would like to know if there is specific testing I can have done for this. I am either loading up on immodium or on laxatives because I am so sick. Any advise or thoughts would be appriciated ☺ sorry about my spelling!
