My bypass surgery was 18 months ago. I have experienced 2 recent episodes where my stomach area is extremely painful. It lasts about 24 hours, with lingering pain/soreness for a few days. Anyone else have this? Cause? Treatment?

It could be any number of things related or unrelated to your surgery so definitely get seen sooner than later. What helps figure it out quicker is knowing exactly where the pain is, so be clear when being evaluated.

(Disclaimer: I really don’t recommend self diagnosis because it’s a slippery slope to self treatment so these are just to help you inform your doctor better.)
