Hi!
I would go see your Dr. and ask him if he knows of any medication that may help. But keep in mind that because of your disease your body may telling you something. That does not mean I'm adverse to tattoos, I'm not I have A fabulous one on my back of the solar system.
One thing for sure is that I would tell your Dr. what happened. He/She may be against tattoos, but he/she may not, sometimes they surprise you! It also may be a symptom of something else. It's never wrong to caution on the side of safety!
Of course it could be just beacause tattoos hurt like H

LL!
Good Luck!
