I don't think Entocort would cause itching and pain in the genital area... It sounds unrelated to the colitis to me, unless you are somehow getting stool in that area when having a BM - a recto-vaginal fistula can cause problems in that area.
I'd recommend calmoseptine for butt burn caused by diarrhoea, but for the genitals I dunno. It could be a yeast infection. You should probably see your doctor about
