I need to know where to get novacaine gel for tatoos could someone help me out?

Why? Tattoos don't hurt that much and if you (they) think they do, then they probably aren't the best idea anyway.

Some people have a low pain tolerance but also have a strong desire to be inked.

I've posted a similar question, you can look here to see what sort of answers I got...
