Hey guys, I have a week and a half old tattoo that's been healing fine and I've been looking after as standard, but yesterday I noticed a small raised bump with a slight red rash around it on one area of the tattoo. It's not sore, itchy, there's no oozing, and as far as I can tell it doesn't feel particularly warm, but I'm concerned about it being a sign of infection. My skin is a bit sensitive at times and I know pimples aren't too uncommon, but I was wondering if this is something to worry about? Thanks all.
