I have to agree with Duce and Grandad. I got my fish tattoo done a 2 months a go and I was bricking it for the few days before having it. But it was nowhere near as bad as thought it would be.
The outline is just like a scratching feeling and the shading is a slight burning feeling but it was very bearable. Kinda get used to it when you've been lying there for 2 hours having it done.
The next few hours after is probably the worse with it stinging TBH. Definatly get more done in the future.
