Tattoo and anxiety

Patient: I had a tattoo done with india ink a few months ago and had a pannic attack whilst doing it, i assumed it was blood poisoning and we called an ambulance. They said it was fine, as has our local doctor. I was taken to hospital in an ambulance again a few weeks later and they checked my blood and everything and said I was ok. A small area of the tattoo is slightly skin coloured (looks faded) and is numb to poke with my nail, it feels like a line lump, is this ok?
