Question: How long does it take for petechiae to go away?
And what are the causes?
Answers:
Petechiae are bruises. They last a week or so and may be from scratching the skin or from internal pressure like vomiting or coughing. If they keep coming or there is no reason you can find for getting them, see the doctor for a blood count to make sure your blood clots normally.
