Behcets and Tattoos

Hi, I was diagnosed years ago with behcets but have been very lucky since not to have too many flair ups. I really want to get a tattoo but am not sure if this is a wise move given the positive pathergy test diagnosis for behcets. I was wondering if anyone had any problems with behcets and tattoos or any advice as to whether or not I should steer clear or should not have any problems.
