If i've had a temperature between 101-102 for a week every time the advil (ibuprofen) wears off. when should i be concerned it is more serious than a simple flu?

If Fever Continues: Flu can give a high fever for the first week (full 7dd) of illness but often improves by week #2 or sooner. If still w. A high fever >=101 tomorrow then you definitely should be seen. Flu can lower your immune system and most common complication is pnuemonia or possibly other secondary infections which may need an entirely different treatment than just for flu alone.

See your doctor asap: Fever for a week is more than flu.Sometimes flu can lead to secondary infection like pneumonia.See your pcp as soon as possible to find the underlying cause of this fever.
