My 7 year old went to the ER two days ago and got and IV for dehydration (they did blood work and ruled out appendicitis). He was vomiting for 36 hours (about 17 times) with a stomach ache, wasn t urinating and had no fever. He slept the following day (All day) and couldn t get him to eat or drink then today he said he felt a bit better, however, he now has a fever of 102.4 and again has slept ALL day. (been awake about 4 hours). I have been giving him tylenol but nothing seems to be helping.
