Starting the night before last night I've noticed little red dots have been appearing over night on mainly my left forearm. The first time I noticed them (yesterday morning) there were two. I didn't think much of it until today they increased in numbers (from two to nine). The new seven appeared in a curved line up my forearm. They don't itch and I've rarely ever been biten by bugs, even then they were never like this. I noticed a lot of my symptoms match Petechiae but I'm not completely sure. Can you help?
