Scratches on my back

Question

I am a 17 year old guy and I have like 3-4 horizontal lines on my back that look like scratches and I've had them for some time now. They don't hurt or itch or anything, I cant feel them, you can only see them. I play video games or sit on the computer a lot, could it be from an awkward sitting position or something? I have no clue where they come from lol, it just looks funny and I wouldn't mind if I could get rid of them. Thanks =D

Answer 5

(does the chair you sit in have lines down the back?)it could possibly come from that just leaving marks on your skin
