I don’t have anything that severe, but I watch my diet VERY closely. I do have short bouts of tremendous, double over cramping, so I empathize with your daughters pain. You don’t mention anything about the foods she’s eating. If it were me, I’d find a clinical nutritionist to see if she can’t find relief that way. Meds are always my last resort. Solve the problem not cover it over. Gluten free is the best place to start when it comes to intestinal/stomach issues. Wishing you both the best ❤
