I just saw this. When did you get your tattoo? It may just be healing. Tattoos get extreamlyitchy and scab up. It is totally normal! Just keep the tattoo moist with some A&D ointment or neosporin. Never use alcahol! Do not scratch it! It may make the color come out and then you'll have a yucky tattoo with spots in it. If you need anything else letme know! If it is a new tattoo just do what i said above and it will heal in a couple weeks. No need for a doctor. If it's an older tattoo that just started doing this go to the doctor then. You may be allergic to something.
