Ulcerative Colitis
"(2005) Diagnosed with UC in Australia.  I was hospitalized and put on some very strong doses of Prednisone/Cortisone. first as tablets and then via IV. It made me very irritable and made me worse. I ended up getting a subtotal collectomy/j-pouch (&amp; full recovery)

(2015)  a few weeks ago, I got a really bad case of poison oak. To treat this I was given a cortisone shot and prednisone to take for a week. For the first time in 10 years  and post-surgery I had a flair up with blood in my stool and the urgency to go to the toilet. I stopped the prednisone immediately and it has since subsided. but it gave a me a scare! If you read the side effects it very rarely can exacerbate UC conditions. be mindful if you arent getting better to reevaluate!"
