Got my first tattoo!

Mo
I made a post about two weeks ago about me getting a tattoo and I finally got it - I love it! The pain was completely bearable and a lot better than I expected, it only took about 25-30 minutes! 
And here it is after removing the wrapping! (albeit a little raised and swollen ahaha):
The only thing is, I actually noticed a rash kind of thing underneath it, does anyone know what this is, and if it's nothing to worry about?!
