Okay, For the last 4 years, I have had cramps in my abdomen that has caused pain and diarrhoea (latter in more extreme cases). Initial cause was parasites found in my abdomen, I took medication and was relieved of these symptoms. Although after 3 months, pains came back but without any indicator in my Stool samples or blood tests. Had a suspicion it was gluten related. Although have hardly had a problem with Pizza Base. Although, say, White bread toasted has caused me a lot of problems.
