@ejlouboutin16 I have a similar problem. I am not sure where the blood comes from but I have coincidentally come to realize very recently (as in the last few weeks) that I either have lactose intolerance or IBD (Inflammatory Bowel Disease). From what I have been able to determine, with just lactose intolerance there is not generally blood in a person's stools which is why I now wonder about IBD. I plan to try to isolate what else other than lactose containing foods may be causing problems for me, and then I plan to make an appointment with a gastroenterologist.
I too have bloating and pressure.
I suggest you make an appointment with a gastro and try to get to the bottom of it. If you do, and if you find anything out, please let me know and I will do the same if I make it to the doctor. The doctor I would like to see is scheduling in September or October so I may have to settle for someone else.
