YES! Check this out with a gastroenterologist. It sounds like steatorrhea, a symptom of celiac disease. I had painful bouts of diarrhea-like symptoms that felt like a hot knife in my lower abdomen. . . until I went on the gluten-free diet. Celiac disease can lead to cancer, and also to terrible birth defects if your children inherit it, as well as ruin your current quality of life, so definitely see a specialist right away.
