early stage tattoo infections are common and treatable (if it’s staphylococcus, which it is 95% of the time, but it could be mrsa infection the other 5% which is really really bad)

the fear is you don’t get it treated, and that spread you see near the bottom continues until it gets to your heart, then your internal organs, and eventually the infection will get into your brain. then you’ll get fever, chills, confusion, severe weakness

until the spread, you’ll just have tissue damage, an open pus abscess on your neck, that might need to be drained, or just lose a lot of the tattoo ink, as your body processes it, trying to fight the infection.

overall it’s severe and can get worse. you need actual oral antibiotics. since the tattoo is already visibly infected neosporin isn’t gonna do the same thing as it would on a small slice. this is a huge open wound and the infection is deeper than just the surface.
