Dizzi,
You do sound very similar to me now, and also back when I perforated. I may be wrong, but it seems that they have difficulty identifying the full extent of problems active in the ileum, where my scarring and inflammation is located as well now and back when I perforated. In my case the scope will not reach past the ileocecal valve and all evidence of problems in the ileum is from the small bowel follow through (sbft) imaging. And almost 16 years ago when I perforated, even the sbft didn't show "anything conclusive" as late as a week before perforating. I think imaging is a lot more refined now though. But certainly not perfect in our area of disease.
They kept throwing prednisone at me as well which helps with inflammation and maybe spasms, although does not help scarring. But that is the best they could do then, and it seems that is the same thing they are treating us with now. I'm having the same symptoms, tests, treatments, reactions ect. now as back then. And sounds the same as you. Prednisone did take away the 15 urgent trips to the john with D. Now it's just the opposite and have extreme constipation and going only every 4 - 5 days if lucky. And then it's like passing boulders some times. And like you, I can certainly feel the pain in the lower right quadrant and at times spiking out to the pelvic area.
From past experience, all I can tell you is watch your temperature along with all the other symptoms. If my temp gets anywhere around 101+, in a lot of pain, bloating and ill feeling, I will be heading for the ER. Of course though by that time it's possible it's already leaking into the abdomen. And believe my past experience, that is not good and it takes twice as long to recover after surgery. It can be life threatening if you wait too long and try to tough it out. When I finally went they told me afterwards that I was close to having organs shut down from the septic shock. I replied..."tried to tell you doc but remember, there was nothing conclusive!"...
