I havent been diagnosed with IBS but sometimes i feel sick to my stomach like ive come down with a stomach bug all at once but i never puke i always use the bathroom and sometimes its diarrhea and sometimes its just soft stools with mucus in it and ive a few times pushed out small balls of just mucus and every time i have to have a bowel movement my chest aches and left arm aches and stomach hurts... Ive told this to a cardiologist on multiple occasions but they said my heart is totally fine but i do suffer from GERD and Anxiety disorder
