For about a year now I've had these strange long almost
gash like marks along my back and butt. I've tried two doctors over the year and neither could offer any real explanation but just tonight I noticed a strange lump, and it is migrating up and down one of the marks! I took a picture (don't worry it's of the side of my thigh) showing some of the streaks and the weird "lump". Somebody please help me I'm getting scared!

Anybody got any ideas what these marks are from?
