I had severe cramping after my Whipple. It happened if I ate something too fatty or rich. Since I now avoid those things like potato chips, ice cream , deep-fried foods, etc, I rarely get that. As each year went by (it's been 4 years since my Whipple & chemo), I can eat a wee bit of some of those things and no longer have that. For me, it was gas ! Yes, the pain was really sharp sometimes and I could hardly breath for about a minute or two. I guess it's my innards (what's left !) screaming NOOOOO fat !
