I have a three year old thats has a really bad cough that when he coughs he starts bleeding from his nose or mouth I was wondering what it could be. I took him with several doctors and all say a different thing like one said cause he was picking his nose the 2 said he had anemia now the 3rd said is allergies and bronchitis. If anybody has when thru this can you please let me know what it means or what it could be. Thank you...
