You can take Tylenol if the pain is getting difficult to tolerate, but you cannot take Ibuprofen (Advil/Motrin) as they are counter-indicated for people with our condition.
Otherwise, you can adopt a soft diet and abstain from eating fiber, uncooked veggies or fruits and whole grain products. It will give your bowel a short break, which could help reduce inflammation and the associated pain.
The last and best option in my opinion is cannabis, either inhaled via vaporization or eaten. Cannabis eliminates epigastric pain almost instantly via inhalation, but Indiana is not a MMJ friendly state as far as I know, but maybe you know people who use it (either medicinally or recreationally).
Your nurse was correct to say the pain is normal, but it doesn't mean it shouldn't be treated at least slightly.
