text: petechiae -symptoms of what? besides dengue fever, what other diseases have petechiae as symptoms (petechiae can also appear in singles and not just clusters, right?) i'm a bit worried because i noticed i've been having petechiae for some time now (few ones, but they're growing in number), and am not in a position where i can just drive to the hospital to have myself checked. is having a few petechiae something to worry about? no idea
