The past few weeks I have been getting strange bites and lines all over my legs. At first they seemed like mosquito bites. However, I kept getting them and they began to start forming first into lines of three distinct bites, and now I have a few inch and a half long, squiggly lines on my legs. They look slightly scabby, but are red and raised. They itch only moderatly, like a mosquito bite. I also have some normal bites mixed in with these weird ones, but I think those are mosquito bites. I have already gone to the doctor to see if I had gotten scabies but aside from the red lines the symptoms don't match up. I have looked for bedbugs, fleas, etc. And have been scouring the internet for some idea of what could be causing these marks. If anyone can give me some insight or any ideas as to what it could be I would be very thankful.
