The problem with UC is that the drug protocol is limited and it appears you have tried all medical treatments with the exception of Remicade. It's a tough balancing act; I can understand your hesitation with taking Remicade (I wouldn't wanted to have taken it either) but on the same hand your risk for colon cancer increases dramatically if you aren't able to keep the inflammation down. So, maybe you should look at some alternative treatments to complement what you are doing?
