Skin rejecting tattoo ink?

If you've never had a reaction to the ink before, it seems kind of strange that you are now. I developed a rash and after I stopped using the A & D it went away. I went for my next session and got it again. I think it may come having your skin be somewhat overworked, which if you get a larger piece and are used to the pain can happen pretty easily. I would wait before going to see a dermatologist, doesn't seem like it's anthing too serious. If it persists for more than a week then maybe set an appointment. Did he use a different type of ink that you are used to? Are you using something different than A & D? You could have developed an allergic reaction to anything along the way. Hell, you could be allergic to your laundry detergent and with the clothes against the fresh tat it could be giving you a rash. Wait it out for a bit and see if it goes away after changing things up a bit. Good luck!
