Undecided Question

Infected tattoo can I sue?

Me and two of my friends went and go tattoos exactly one week from today. My 1 friend and I had the same tattoo artist. Both of my friends tattoos turned out so-so, but mine turned out to be a mess. This is not my first tattoo, so I know how to take care of them. The tattoo when getting done had to be the most painful one I ever gotten and I knew right there something was wrong. A few hours later my tattoo swelled really bad and the redness started going down my arm. ( the tattoo is on my wrist) Then my tattoo started to puss and I realized that there is like a chunk of my skin missing as if the tattoo artist went way too deep. I called the tattoo parlor and asked them what to do and went down to show them and they blew me off blaming me and just walked away. It is now a week later and my tattoo is still swollen, red, pussing, and extremely painful. I did not sign a waiver none of us did.
