I've been on Entocort now for two weeks. My ulceration and Crohn's is in the Illium and up the small intestine. The first 3 days were hell for me with an acidic feeling that started upper abdo and moved to be very painful in the mid gut section below the belly button where I normally am sore. I've never had that acidic feeling in the gut before, though I've occasionally had it in the small intestine.
It also takes me hours to get to sleep, and sometimes most the night.
On the other hand my lower back pain has been gone, and for a week after those 3 days my mid abdo seemed more relaxed and not sore. The anxiety has gone too, but sleep is still a matter of being awake for hours. Unfortunately the soreness has returned now...but I'm hoping it isn't because the drug isn't working. Also my nausea is generally better, and though I've had mushy stools I haven't yet had full on 'd', which is unusual.
My problem is that I am also supposed to have IBS (and coeliac disease too), so I don't know how much that is playing a role too.
I really hope that in a month or so I'll start to feel way better than before with better sleep, less occasional acidic feeling, and an overall better quality of life.
