Hi Kazza and welcome to the Healingwell Crohns forum. Yes when flaring is normal to have the pain in the lower right area. Many have this happen to them too.
I take the sister med to Lialda, called Asacol. Its one of the 5ASA meds used with IBD diseases. I have been in remission on the Asacol for the past five years.
Many GI's are now trying the top down approach on the Crohns meds. Personally I think it wouldn't hurt to try 6mp or Imuran first. We have members on this forum who have been maintained with one of these meds for over 10 yrs. They have a pretty good record for many. And now while you are on Pred it might not hurt to get on one of them now as they take about
3-4 mos to reach full efficacy.
Hope I have helped a little. Ask anything questions you might have, one of our great members will probably have an answer for you.
