Hi, I have 5 day old tattoo. It is covering a large section of my upper and lower arm. The tattoo is quite dense so there is allot of scabbing. It seems to be healing well and there is no sign of infection, however, there is a very odd odour. It does not smell foul, just unpleasant, almost like a squished insect, as bizarre as that may sound. What could be causing this, also, is is cause for concern?
