Jolene asked earlier if other zebras too had pinpoints red dots all over (she called them petechiae). Here are mine :)
They don't itch and looks like someone sprayed tiny speckles of red paint on my skin. They are mostly on my arms and upper body, are completely flat and don't disappear, even if you press them. Got plenty of angiomas too, but they are not flat. The speckles seems to increase with sun light, but they never go away. Had them since I was a child. Unlike other zebras who also have them I don't have thyroid problems or high blood pressure nor use ibuprofen or pressure cuffs, so I'm guessing it's a zebra thing.
