Can I get a tattoo if I have dermagraphic urticaria?

I have chronic urticaria, cholinergic, cold and dermagraphism, I take an an antihistamine daily which keeps it at bay but I've recently been thinking of getting a tattoo and wondered if anybody would know if it would be possible. Would the swelling make it difficult for the tattoo artist? Should I expect any long term problems?

Trust me on this one, it won't be worth giving it a shot. You could take extra antihistimines but since you've never had a tattoo, you don't know how your skin will react to the dye from the ink or the irritation from the needle.
Some people with this condition report that ink tries to come out of the skin during the healing process so you can get a 'blur' effect or a lighter tattoo. If your body is naturally fighting allergies and reacts to what the 'average' person can handle, then it only makes sense that this kind of irritation and ink would cause a pretty serious swell reaction not just during the actual tattoo but also during the healing stage, which causes a lot of response from your skin (redness, itching, flaking...like a really bad sunburn). Each persons' skin is different but those who are susceptible to irritated skin reactions may not end up with a good tattoo.
My advice (if you're hell bent on it) would be to try a small one in an area that's not visible to see how it heals and how your skin reacts. I've heard a lot of stories that ink can't 'heal out' of your skin once it's there, but I've also seen a lot of tattoos that have varying degrees of darkness and sharpness based on healing and after care.
So do yourself a favor and skip it...the main reason being that a bad tattoo is worse than no tattoo at all in a situation where you can't be sure if it will heal or take properly.
Also, if you go through with it, take those extra antihistimines and tell your tattoo artist before to ask his advice. Some artists guarantee touchups if it heals improperly which may also help you. Good luck...think it through because tattoos are forever and if you have a bad reaction...it's one you'll never forget, that's for sure!

I know u don't probably want a lecture, but...
you find someone that will tattoo you with that condition, it's not going to be pretty...I know that an artist that is familiar with that would NOT DO IT unless they needed money really bad...or
you try it, and swell, it's not going to heal right, and look horrible.. ..most likely the artist would have a complete freak out.
Ask your Doctor for their advise, because I am not one, but I have worked in a tattoo shop.
But whatever you decide, the best of luck to you.
