My 10 yo daughter has Asperger s syndrome and sensory processing disorder. She tantrums frequently and suffers from anxiety. For about the past year she gets nose bleeds every time she gets even slightly upset. She s not taking any prescription medication. What is causing her to bleed when she s upset? It happens almost every day and a few times a day. It doesn t bleed for more than a few minutes each time but it scares me and her as well.
