Multiple causes: It sounds like an irritation in the GI tract. See if there is a relationship to menstrual cycle, constipation, diarrhea, gas or bloating. See if lying down bringing legs up helps, or hot water bottle. Ginger tea is often settling and so is thyme , 1 t of dried herb in a cup of boiled water, steep for 5 minutes. See healing digestive disorders by andrew gaeddert for his kitchen pharmacy.
