I got a tattoo when I turned 19. It's a plain black ink symbol on my upper right arm. It is completely black. It's been just about 3 year and I'm starting to think something may be wrong. It will randomly get puffy,itchy,the swollen parts get kinda hard,randomly burn,randomly sting where it feels like needles are stabbing into it(which is happening now),or any combination of those things. It's starting to drive me nuts. I've heard anything from allergies to heat(which is unlikely as I'm cold and it's been rather chilly lately)to scarring to diseases lol. I dunno I would just like some advice :/
