'no pain'?

Hello everyone !

First of all I would like to say, that I'm not English and that's why I'm gonna ask about very important thing for me. I've got idea to tattoo sentence on my hand but I'm not sure if this sentence, which I'm gonna translate from my own language is correct in English. I mean a sentence "Feeling no pain, I am nothing". I know that 'no pain' is not well said. I've got the same in my language. This word doesn't exist and i know about it but this word in my language has got specific meaning , it's word to interpretation. It doesn't exist and it's not well said but it has got very important meaning for me. I don't wanna change this sentence like 'when im not feeling pain, im nothing'. It must stay like 'no pain'. The thing is now, if you can know the meaning? Is it possible? Is it well said and can you interpret it? I hope you understand me, it's very diffucult to explain it in other language.

Thanks a lot
