Last night I noticed a long, thin, red raised line, (resembling a scratch), wrapping around the side of my torso. There were about 7 or 8 other similar ones on my chest, arm, and stomach. They were different lengths and some of them were in a pattern that looked like scratches from the nails of an animal. They do not itch and I did not scrape, injur, or scratch myself in these areas at any time in at least a week. This morning there are more of them, on my arms, shoulder, upper thigh, and torso areas. 1 or 2 of them have a "criss-cross" pattern like "tic-tak-toe" or like a lattice pattern. I have found where several people on the internet have tried to describe the same type of rash-like characteristics, some with pictures, but there doesn't seem to be any follow-up or resolution as to what this is or what is causing it. I haven't had a fever and I feel normal in all other respects with the exception of a mild headache, which may or may not be related.
Has anyone figured out or found out what this might be?
