Small Rash/Blisters

Around an area that I got tattooed on Friday three small - what looks like blisters have developed - around 1mm in diameter. Is this normal? Maybe a reaction the the colour or maybe a shaving rash? I had to sweat this piece for longer than my others as they on my chest. They are about halfway up my forearm. Here is a link to a pic. http://img167.imageshack.us/img167/1754/002eb2.jpg
