I think a lot of things can have an affect on felt pain... placement, your state of mind, general health, etc. Do what they recommend, rest, good meal before, hydrated, take a snack along and you'll be fine. Just stay calm and don't make it worse than it is. Maybe let everyone know where you're getting it for more specific advice.
I’m pretty new to this site so sorry if i don’t really understand how to work it, but i’m getting my second tattoo tomorrow and i’m excited but also nervous because it’s a different body part i’ve never gotten tattooed before AND it’s a different design and style of tattoo than my first so i’m not sure what to expect besides the feeling of getting repeatedly stabbed by a needle lol. I’m mostly just nervous about the pain where it’s going to be located, i’m not expecting it to be painless because let’s be real pretty much all tattoos have some pain.
