newly diagnosed ibs questions

hi!! i am experiencing the worst bowel issues randomly, i get insanely sweaty, hot, feel like i’m going to pass out, and my stomach hurts so bad that i NEED to run to the bathroom. what is causing it??? it happens so randomly and i can’t tell if it’s concerning or normal, i do take prescription medicine for ibs, but i still have to use the bathroom 4+ times daily and some days this will happen, what am i doing or should do differently?? is this normal??
