Started on my throat yesterday, was expecting it to be the most painful yet but found it surprisingly easy. The ditch and middle part of the fingers were worst for me so far
For least painful, has to be the finger nail, feels pretty good. My fiancée got her ear done last week and said the same about that, no pain, just vibrations
Definitely the inner elbow was most painful for me. Got the middle joints of my fingers done last week wasn't to pleasant either, already booked to get them redone on the 27th as the ink didn't hold very well at all!
