No real pain for me 1700 FUE, i have plenty of tattoos, on a pain scale i would put tattoos at a 6 or 7 depending on where you have it, FUE HT i would put on the scale as a 1, in fact the injections at the beginning were the worst part but even that was only a 2 on the scale. Root canal pain, now that is the mother of pains.
