It always starts after I pass stools. After passing stools, I feel uneasy in my stomach with slight pain which keeps shifting. Sometimes up, down and sometimes on sides. I pass stools after 2-3 days after taking psyllium husk. But after passing stools, this uneasiness comes in and stays till next morning. I am perfectly normal till the time I pass stools. My stool passing is not regular. Is this ibs or something else? Please advise.
