It can honestly depend on where on your body you have them. I have 4.....one on my rear shoulder blade, one one each upper arm and a large dragon down the outer lower leg.
The first three were just like scratches with an after pain of mild sunburn for a day or two but the one down my leg bought a little tear to my eye at times.
Generally speaking, legs, ankles, wrists, ribs and anywhere very close to a bone or very fleshy might nip a bit.
Go for it. Once the tattooist starts, you'll be fine
