Well, that sounds absolutely terrible. I'm sure sorry to hear you are this uncomfortable and for SO long! Did they originally diagnose you with gastroenteritis? I'm assuming so since they gave you flagyl. The problem is, that then sometimes we get other stomach issues when we take an antibiotic. i would recommend a probiotic. This helps balance the bacteria adding in the 'good' baceria we need. You can eat the probiotic in a premade smoothie or at least they sell that here in the states in the dairy aisle or you can take a supplement (pill). Pill might be best for you at this stage. Do you mean that you have this discomfort during a bowel movement or is it at other times?
