I Have Had Peptic Ulcers In The Stomach. Well From

I have had peptic ulcers in the stomach. Well from that but now I am hurting on my right side with diaherra.Usually I can take imodium and it will go away. I am going on my 2 day of diaherra with no help from the imodium. I was just wondering if I may have an ulcer somewhere in my colon? Is that maybe a possibility?
