Tattoo vs urticaria&type1

Hi there, I have been doing dafne for almost 5 years now, and an overall success for me apart from dawn phenonoms (which have accepted just one of those things). My long term blood test doctor happy with and lost weight through gym and eating when want, and not go treat. Been thinking for a while of getting a tattoo, and being doing lot of research. I have urticaria (aka stinging nettle rash) I have not had a flare up for few years now think due to better control, and general health as tends to flare up when ill(infection) of run down. Just want some advice so I don't make a mistake that will live to regret, with flare up or it permently returning. Just feel it's something I want to tick of bucket list. Any help or advice appreciated??
