What can sandy textured diarrhea with abdominal pain mean? I have previously been diagnosed with Crohn's disease and had it for the past few days.

Call your GI doc. Crohn's is a chronic disease that can wax and wane over the course of one's life. Diarrhea is a symptom of crohn's disease. Crohn's activity should be treated with appropriate anti-inflammatory medications. Call your doctor.
