I’m not sure what that pain is. My pain always came and still happens sometimes when I either eat too much at a sitting or consume too much sugary food. My pain is a cramping at the top of my stomach. At times it can take me down for 15-30 mins. It always goes away as my stomach eventually digests the food. My Whipple was in June 2023 and my last chemo treatment was Nov 2023. The pain I experienced was even worse while I was going through my treatments. It would occur almost every morning after breakfast. It only occurs now when I eat more than I should or I eat too much sugary foods. I hope this helps.

I am 2+ years out post Whipple and I still get pain across upper abdomen, under my ribs.
Luckily it only lasts a few minutes but is very intense.
I can’t link it to anything, but in past it was after spicy food, so thinking it’s gas build up?

Over 2 years after the Whipple for me: what you are experiencing sounds like the gas movements I have. I would never have believed gas hurt so much! And my pancreatic cancer has now moved into peritoneal carcinomatosis--what works for me is a little walk (indoor or outdoor) after eating, camomile and peppermint tea (plain), and yes, Gas X. If diarrhea accompanies, Immodium now has an extra ingredient for soothing. And a heating pad occasionally. Pain-wise, I feel good; tired and weak, not so good. I hope some things you have control over might help you a bit...Carrie (85 years and hoping for another)
