Hi, I was diagnosed with crohns 18 months ago. I work as a paramedic in London and am worried as my consultant wants to start me on azathioprine after my first 3 months on steroids. I understand that this has some nasty side effects and reduces your immune system. My job involves constantly working with very sick people who usually are undiagnosed. I have young children and would dread the thought of catching and passing things on to them due to this. Sorry for introducing myself with a question, this is my first time on a forum.
