Is it right?

Welcome to A2K, wwl. That is a stunning line of poetic consequence. It is a way of saying that someone bit another on the shoulder with malicious intent, and the scar became like a tattoo, bleached white as a result of blood sucking. (which is what leeches do, you know)

It is, most likely, metaphorical, and a response to a wounded soul.

That's a great help. I originally took the word "place" as somewhere the author stayed,now I know it refer to the place in his shoulder that he wounded.
Thank you.
