What Causes Hard Abdominal Area And Persistent Rectal Bleeding?

I was diagnosed with chrones about 12 years ago. I went into remission according to my G.I. when I was pregnant. For the last 3 years now I have been having all the same issues I did when I was diagnosed. My G.I. retired and the new one has done 1 colon oscapy over the last few years he says I don t have crones and was miss diagnosed but I have 6 different pathologist reports from before that say I do have it. I don t know what to do I m sick all the time and have been bleeding off and on now for a while but my doctor won t do anything and says its my diet. I m a bigger girl and the top half of my stomach is rock hard well the bottom is soft now. It don t hurt there much but I m worried it has something to do with the chrones. What do you recamend? Is it possible for the pathologist reports to be incorrect even though the meds I was on at the time helped me?
