Hi my 16 months old daughter has been having a fever for 6 days now, while she was shivering her lips turned purple, temperature up to 100.5 and sometimes over, her urine has a strong smell to it, I took her to the emergency on the 4th day of her fever and just told me to keep giving her Advil. I called the paramedics to check her on today, she has no chest infections or ear infections she s breathing fine. What s causing this fever to go on for 6 days?
