A bump

Ok, so i got a tatto of a star below my stomach on the right side right below my waist line on the 25th. The next day I woke up to a big bump not on the tattoo but a few inches below it, and it's as hard as a bone almost and is only sore when i bump it against something. My friends who have tattoos told me this is normal and that it should go away in a few days but I still have it. Is this normal? or does anyone have any idea what it is?

could bwe lots of things.cist,boil,ingrown hair,or a swollen lymphnoid.with the area youre talking about it is quite possibile it is a swollen or infalmed lymphnoid.keep a eye on it if it gets worse or dosent get better in the next couple days may want to have a doc look at it.hard saying EXACTLY what it is best of luck
