Question: My 5 year old son had an episode of the croup that brought us to the ER on December 16th at 2:30 am. He was treated with a neb and steroid shot in the glute. He was admitted for observation and CBC was done. He was released the following afternoon showing great improvement. The following night he presented a fever of 101.5. The fever remained 101 for the next 24 but dropped to 99 for 5 more days. The third day he started having severe stomach pain. this lasted for about 48 hours and he quit eating aolid food. He also developed flu symptoms, coughing, sneezing, and thick mucus and running nose. Once the fever subsided he was left with runny nose and severe cough. This lasted for 4 more days. On the 8th day he seveloped a rash on his legs and swelling in his knees and ankles. The rash turned out to be a vasculitis. Little bruises all over. Upon his follow up visit for the croup on day 11, he was given another CBC and a UA for suspition of Hochem_Scholein Purpura. His testing came back with Thrombocytosis and Toxic Granulation. His platelets count was 649 and SED was 29. We are now waiting for our follow up on Wednesday. The first bruises are fading but each day there are new ones.
XXXXXXX is my child that gets everything, wierd illnesses that none of my other children come done with. In the past he had a illness that caused him to seep blood from his gumline for 3 days. The doctors said he had hand, foot and mouth although he never presented with the rash on his palms and feet and had no sores in his mouth at all. Also, none of the other children around him came down with it, including my other children in the home. This is just one example of his pasthealth history.

My question is, should I wait until Wednesday to take him back in or should I take him to Children's hospital?
