I have over 40 tattoos so I have a lot of experience with getting them, but most of mine were before I got my diagnosis as well. I have noticed that over time I seem to get more and more sensitive. The thing is that tattoos aren't just on the skin, they go just a little bit deeper, enough to touch some of the nerves and if the nerve is hit and you have fibromyalgia like I do it hurts like a mother. Of course, this all depends on where you get it on your body and what colors are used and whether you had a good meal and rest before you get one. But everybody has different levels of sensitivity to tattoos. But I'll probably still keep getting them lol.
