scab on tattoo?

[kaitlin]

Hello! I just got this tattoo four days ago (if you include the day you got it while counting?) and I am worried about one part of it. There is one section that is like really thick and crusty, a little red around it, and warmer than the other parts of my skin. However, it isn’t smelly, oozing, or itchy. It does hurt a bit, but it may just be because of how thick the scab/crusty bits are and how close it is to the inside of my elbow. I’ve attached some photos. Please help, I’m just worried it’s infected (I’ve been taking care of it though I promise).

It looks a bit overworked, which would account for the redness and swelling. 

If it persists, gets hot to the touch and/or puss-y then you've got a problem.

Keep it clean. Don't put anything else on it. If it fills with pus, go to the doctor.
