Hi, My 5 year old daughter, whom is IgA deficient, had a bout of acute ideopathic thrombocytopenia purpura nearly 2 years ago. She has been fine since then. However, a few months ago she had a decrease in appetite and began complaining of a sore throat and belly ache. She has no fever though and her throat is not red, she isn t constipated,vomiting or having diarrhea. She has increased urination as well as some pain while urinating. In the last month or so, she keeps having episodes of petechial bruising. Sometimes I know she had been rough housing, other times I have know idea how it came about and today she developed it from the cuff of her clothing sleeve. I m wondering if these things could be related and should we return to the dr for some bloodwork?

Summarized question: What causes vomiting in a child when diagnosed with thrombocytopenia purpura?
