My girlfriend and i got the exact same tattoo about a week ago. Mine is absolutly fine and is healing well but hers seems to be pussing slightly. Some of the ink has turned a kind of dark brown colour and it is painfull to touch. It is only a little tattoo on the wrist and the only difference between us is that mine was shaded in with a shader but when she had hers done the shader was broken so the artist coloured it in with a liner. Is this a serious issue?
