I is a possibility it is IBS which is most commonly expressed as abdomonal pain, cramps, and diahrea or constipation. IBS caused by and/or aggravated by stress, trigger foods ie. alcohol, coffee, sugar, fats, shakes, dairy etc. There are many many trigger foods and makes us strickly limit our diet to find out what foods are okay and what are not. Some people go for the medication root but when I tried that it hid the crampindg symptom but created a much worse symptom later so I manage it with my diet and stress. 25% of woman have it and I think something like 15% of men. There is no diagnostic test but there are many websited that describe the diet and it truly can be managed easily if you can commit to it.
