I was just lying down and noticed that I have 5-6 scratches or very shallow cuts along the back part of my hip and lower back. They are a little tender, and they're only on my right side.
I walked a LOT today (inhabitual amount) & it was very, very cold (about 25F). I was wearing three layers, and I had a backpack on. My non-HA idea for what happened is that my clothes or backpack scratched me since I was walking so much. The lines are very straight, though, so I'm not sure. I don't have an animal that could have scratched me. Maybe I scratched myself in the night? My fingernails are a little long.
The scratches are QUITE long though, maybe 6-8 inches each? I don't know how or why I could have scratched myself for that long, since usually scratches are short.
I included a picture. Thanks for the help.
