I think you should be able to get ssi for UC and Chron's. What employer is going to let you go to the bathroom 10-20 times a day. I have a neighbor who has never had back surgery. He has two herniated discs in his back and he is sitting on ssi. He is outside working on his car and having parties until all hours of the night. Now if you ask me he is someone who can work and he is getting ssi and then there are people who really need it who can't get it. I know he hired a lawyer though. You might have to do that. Good Luck!
