I totally agree with starting the hydrocort enemas and cortifoam. I use both when I feel symptoms coming on and usually they work pretty quick. Cortifoam during the day and enema at night.
I'm in Ontario as well, not sure if you've tried BIO_K PLUS probiotic, I get it at Zehrs, Superstore or health food store and it is amazing. Its fermented milk(wont bother you if your lactose intolerant) and comes in many flavours and its about $40 for 12 containers but it works to firm up the stools and put the good bacteria back in the colon. i use it daily but when flaring 2x a day. Each container has 50billion bacteria.
