How Can Chronic Diarrhea Be Treated?

i have chronic diarrhea that has changed . It is so bad that I Cannot go into a store as I will start to have major panic mode because I am afraid of getting diarrhea and not making it to the bathroom without feeling the diarrhea is coming. I have had a lot of incidents where I have to know where a bathroom is at. MY husband has been living in q nursing home for 5 years and I have had major attacks where I HAD to call someone in the family to get some clothes out of the car. I went all over me and i was totally humiliated. I had diarrhea all over me and the bathroom. that happened fast. I don t go out anymore. I went to the emergency room 2 days in a row. they tested me for manythings; chrons disease, cdiff, etc. everything came out okay. I was put on lomotil and the very next day i had a normal BM. I then had to go to my family doctor referred me to a gastroenterologist in june. Can this diarrhea be cancer in any part of my body?
