My daughter had a tiny purple bruise thing on her leg. I told her to let me look at it but she proceeded to scratch the living daylights out of it (vigorously!). Not long after, it turned into loads of purple/red spots under the skin which did not disappear with a glass. Has she burst a blood vessel? The rash is under the skin and didn't spread through the night. She complained it was itchy again this morning but I have warned her not to scratch it again!
