Yes, I have had off and on diarrhea for past 2 half weeks, no nausea, no pain. Got scared, ran to ER, they did all kinds of blood test, urine, nothing. I have been highly stressed past four weeks, serious issues in my family. I have history of anxiety. Do I have colon cancer? There has been no bloody diarrhea. ER drs wont tell you anything and they did not do xrays.
