I couldn't find anything on Google, so I thought I'd ask here. I've had a tattoo on my arm for about four months now. It was touched up a month after I got it, so it's been about three months since any work has been done on it. However, last night, it swelled up just a bit - much like it was the day I got it. You could run your fingers over it and feel the outline of the design, run your finger along the contours, as though I had just gotten it done the day before. Today, it's mostly back to normal, but I can still feel it in some places. Has anyone here with tattoos experienced this? The tattoo has been fully healed for some time, and I haven't had this happen before. My best guess is it was just a physiological reaction to cold air, or something else along those lines.
