Hi, I have had IBS for over 20 years. I am careful about what I eat. My symptoms are less than they used to be. I rarely get any pain and if I do it s similar to low down period cramps, but hardly nothing at all. I get loud wind sometimes. Last year there were two occasions when I saw bright red blood on the toilet tissue and on the stool. I had no pain at those times and put it down to straining previously to have a bowel movement. What has worried me a little is that this morning I had a bowel movement and there was bright red blood on the tissue and what looked like a lot in the toilet bowl. I had no pain. Should I have this investigated? The thought of any internal investigations terrifies me!
