Did you get it at a professional tattoo shop, or somewhere else? Most places won't tattoo anyone under 18, some will for 16+ with parental consent. Where you got it concerns me because if it was somewhere other than a sterile shop with professionals your risk of infection likely goes up. Did anyone tell you how to care for it now that you have it? It's not unusual for it to be red and hurt some for the first while but you should really seek the help of a trusted adult who can actually help keep an eye on it in case it does get infected.
