I have IBS for well over 10 years when I was ill in early summer. At first, I thought & feared that I may have colitis again ( I was stricken with it before after having salmonella (food) poisoning from working at Colby College in 1988). I was in agony for nearly 3 months until my personal doctor gave me the correct diagnosis. I still suffer from constipation & occasional diarrhea almost daily Got any ideas?
