If you get it done on your back, be ready for the unbearable pain that you will feel.. Have a tat pretty much on my whole back and after 3 hrs told the guy to quit...Worst pain ever that i endured. Still have another 2-3 hrs to finish it and its been 2 summers since i got it done...
On the arms didn't even hurt, but the back DAMN, worst ever since its hitting the spine 1/2 the time.
