Everyone above has said about
everything I can think of. I have liver disease and sometimes when I have an extreme allergic reaction to a food or medicine, I have the problem you describe. Also, irritable bowel, hormonal changes, stress, aging all play apart. I knew one old guy who said he'd give up his whole pension if he could just take a normal crap again. I would definitely go to the doc and do the sample, there are things you can get from restaurant food or canned food and other stuff like that and infections that cause that kind of problem. I feel so much for you and it is so awful. I mostly just want to say I sympathize and will keep you in my thoughts and prayers.
