I was taking my usual, daily, shower; nothing out of the ordinary there. Then, I got out and began drying myself off. As I made my way to dry my back, I took a quick glance at, what was an ordinary, white towel; I quickly noticed something... out of the ordinary--something worrying. I saw a fairly large mark of blood, splattered on it. I instantly became cautious and nervous; I felt no pain on my body, which did not help my anxiety. I was searching my person in the foggy mirror for the source, but to no avail. I patted the towel on my lower back once more, to find it, but I couldn't--I did, however, cover the towel in even more blood. I continued searching with the towel, but the blood gradually slowed, from what I could tell anyhow, so I just turned a blind eye from it.. still wondering what could have happened to draw blood from myself whilst in the shower.
I still have no clue why I was bleeding, or where.
