A couple of days ago, I was in my friend's pool with a bunch of people, and he asked me "How did you get those scars on your back?". I was like "Scars? What scars? I have scars on my back?"
Apparently, I do. I felt them with my hands a while ago (maybe a month or even two), but never saw them. I never thought anything of it and thought it was just the way I was sitting or something, but that wasn't it. I don't even know how I got these scars, and I don't remember having pain where the scars are.
So my question is : Is it possible that I would get random scars like this?
