Pain level question.

Hi everyone.

I'm new to tattoos though I'm in my mid 40s. 4 months ago I got my first tattoo on the outer right leg (middle of the calf), and a month ago I did get my second piece on the outer left arm and shoulder.

Looking for the next one, I've found 2-3 designs I really like and would like to get them on the back or the inner calf of my left leg, in the middle between knee and ankle on the most fleshly part of the calf. Both are circular designs about 15cm diameter, and mostly heavy blackwork and some dotwork.

My question is where does it hurt more? Back vs inner calf?

Thanks 🙏🙏
