Sorry to hear of your long time struggle Simon66110. I agree with Tony33900, try looking at your diet again. I recently learned from a herbalist and naturalist with over 20 years in the business that actually we should review our blood type to the types of food benefical good for us and not good for us based on our blood type. Most if not all the time, the patient is never told of this, curious to why but oh well at this point.
You can find the list of foods based on your blood type at any local herb store that should have it or online once you know your blood type. There are alot of diet plans out there but once I learned this it makes sense, to start from this point of reference.
Because once the infection or organ defect occurs, it enters the blood stream, hence, "changes the chemistry makeup of the inner body workings. And most of medical tests are off or only looking at certain perimeters missing the actual diagnosis, thats why so many people are searching for their own answers.
I also learned that certain bad infections almost always target the liver which leads to ther issues and organs, that in particlar, to reduce the chemical of creating the bile that suppose to hold the bowel until ready, thus, the occurance of flare ups and issues of related discomfort.
Its got to be at the start of the overall digestion process that starts with our intake of food. I suggest, not already, remove all foods with sugar and their disguised names.
And the prescribed antibotics seems to help but at a cost because it also removes all your good / bad bacteria. So, the ups and downs keep happening because the inner garden (digestive system) has not been replanted, grown and kept strong to fight off the invader causing the inflammation causing the malfunction.
Also, on the bleeding, 1 tsp baking soda in water - can add honey for taste - usually helps or apple cider vinegar with a glass of water should help with the acidity level of the body. Take small sips due to any usage of other meds. Just a thought.
Hope you feel better.
