I have 11 sutures on my head (ράμματα άμα δεν καταλαβαίνεις), and i've gotten them without pain killers cause it was on a dangerous spot.
Talk to me about pain.
Also I've donated blood, once before a month and 3 times last year. I'm not afraid of needles, and I want to do the tattoo as a sybolic symbol and not a show off to my friends. It's just a decision, after that you won't even think about it :')
