question: My 7 year old (good health, average height and weight) has had a fever of up to 103.6 for the past 5 days. no other symptoms, I have been treating the fever when it gets up to 101-102 otherwise letting the body do it s thing with plenty of fluids and rest. Went to dr today, they did lab work and determined its not bacterial, its a virus. Fever still, controlled with motrin and tylenol, and now he developed a welt under his left eye. Started as a pea size and grew to a quarter in an hr or so, it looked full of fluid. Now the welt (hive) has dissipated to puffiness around the eye. Should I be concerned about this new development and take him to ER or is it likely the virus and not something to worry about?
