How long does fever last for flu?

Honestly, my fever lasted 4 days and I could barely sleep because of the blocked nose. Just when you think it is going down, it hits you again at 2 AM. Keep your steam inhaler close to your bed, otherwise sleep is impossible.

Generally, flu fever runs for 3 to 5 days, though the body weakness can stay for a week or more. Make sure you are taking your fluids and checking your temperature twice a day. If it crosses 5 days or if you feel any breathlessness, please visit a clinic immediately.

Beta, flu takes its own sweet time of 4-5 days to leave the body. Along with whatever tablet your doctor gave, try drinking warm tulsi and ginger water twice a day. It relieves the throat congestion and gives some peace.

From what I have observed with my family and friends, the actual high fever stays for 3 days. By the 4th and 5th day, it becomes a mild warm feeling. Just take complete bed rest and don't skip meals even if everything tastes bitter.
