My Back.

[Oren]

My back has 3 long red marks, like cat scratches sort of.
Then are a few more smaller ones. (not caused physically)

They are right on my spine.

They've been like this for a month or so now.

Any ideas?

They look like stretch marks from what i can tell, i got the same thing. if it is the same thing. nothing to bad if they are stretch marks

i got the same but...kinda different, ill tell you what i know. Theyre called stretch marks. Just in case you dont know how they got there i read that they usually appear on pregnant woman, "fat" people, or persons that got taller "slightly" faster than the usual rate of a human, the skin doesnt have enough time to fill the space left when you grow and the stretch marks are "born" haha...or at least something like that, you can always use wikipedia =D. Hope i helped

If it is stretch marks then Bio oil should help get rid of them.
Hopefully they are only stretch marks.

Thanks for the replies, I havn't really noticeably grew in the past few months... hmm...

I've had them for a while, about the exact same. I'm over weight, but those marks rarely come on the back when fat. I had a huge growth spert a bit back, and I think its from that.
