Hi, my 4 year-old son has high fever that won't go away. He has had high fever, in and out, for the last 36 hours. During the first 6 hours of fever he vomited about 10 times. Then the vomit stopped. Prior to this, he had had a rash for about 10 days. The day prior to the appearance of the fever his skin seemed dry. I would have thought the rash had nothing to do with his current condition, except that his skin still looks dry and the rash is now red spots. He still has high fever, around 36 hours from first appeance of fever. One more detail, he has had phlem for about a month. We though it was alergyic.
