Don't have a chest, but my rib tat....hmmm..it was a lil uncomfortable; but bearable.
It depends...is all about how mentally you can resist or hate getting sting (I do),my friends got full front yakuza tatt and that didn't hurt to him,but my cousin got a little ink in the chest and he was crying like a little girl. So if your not afraid of needles go ahead
I havee 2 chest tats && niether hurtedd at all ! (8 tattoos)
I find that if I take my headphones in and listen to my fav music while getting inked it distracts me and helps alittle with the touchy spots.
I have 6 tats and want 4 more
Not too sure about chest but I have 3, one of which is a big one down my side. Took about 6 1/2 hours to do with all the color; it really wasn't that bad, though it all depends on your pain tolerance. Anywhere over bone (i.e. Ribs, hip, shoulder blade, etc) generally tends to be a bit more sensitive. If you have something to distract yourself with - a book to read, someone to talk to, music - it's not as bad. Good luck :)
