I have urticaria (due to home dust and pollens mostly) and take medications daily for the past 5 yrs. I always wanted to get a permanent tattoo done on my wrist. Is it safe? I heard that tattoo ink would mix with blood and cause damage. Is is true? Recently I get some small bumps on my hand due to sun exposure. It goes away if I use sunscreen regularly. Please advice if I should proceed with having a tattoo or not?
